LED Driver and PMIC for DLP/LCOS Pico Projectors
Rev V2
3.0 Functional Description
The M09000 is a highly integrated LED/laser driver and PMIC for projection display applications.
The driver portion consists of three 10-bit LED drivers and a buck-boost converter to generate the voltage
necessary to bias the common anode voltage for the LEDs. The DC-DC converter can operate from a Li-Ion
battery (2.7-4.3 V).
The part is capable of generating the DMD power supplies and includes 2 buck converters: 1.0/1.1/1.2/1.8 V
programmable and 1.8 V, and 2 LDO regulators: 2.5 V and 3.3 V.
Monitor functionality and safety features are integrated as well.
The M09000 can be controlled via the I2C interface.
3.1
User Configurable Registers
The M09000 is controlled by 49 user configurable registers in address locations 0x00 through 0x2E and registers
0x3A and 0x3B. The registers are described in the last section of this data sheet.
At power-up all registers will be set to their default value and the M09000 outputs will be disabled. To make the
M09000 outputs active the MP_EN pin must be pulled high and the registers in Chapter 3 below must have the
appropriate values written to them through the I2C port on the M09000.
Each time the MP_EN pin goes low the registers will be cleared and reset to their default value. When MP_EN is
returned to a high state these registers must be rewritten before the M09000 will be reactivated.
It is not necessary to write all 48 registers. If the default setting of a register is acceptable then it does not need to
be written.
Below is a basic register configuration to enable all the outputs.

The channel associated with each color can be controlled by register.INPUT_CONT[5:0]. If any of INPUT_CONT
pairs of bit [1:0], [3:2] or [5:4] is 11b there is no decoding of the input signal and pin SEL0, SEL1 and PWM control
respectively channel IOUT0, IOUT1 and IOUT2. In this mode of operation the PWM function is disabled. Please
note that the PWM engine can also be shut down to save power by setting INPUT_CONT[7]=1b.
The current is controlled by programming registers.IOUTx.bit[9:0]. Each current step corresponds to 1.17 mA.
It is possible to store preferred value of current into the M09000 in case a particular part is mated with an optical
engine. The default value of the bits setting the output current (register 0x13h through 0x16h) can be programmed
in the internal OTP memory so the white balance point of an engine mated with the M09000 can be stores into the
device. Please refer to the paragraph regarding the OTP memory in Section 3.12 for details on THE programming
procedure.
The M09000 features a PWM to current amplitude modulation converter. The current at the output can scale
proportionally to the duty cycle of the signal applied to pin.PWM. For example, if the duty cycle at the PWM input is
25% the current at the output will be reduced to 25% of the value programmed in the M09000.
The change in the amplitude of the output current as a response to a change in duty cycle of the PWM input is not
instantaneous; the current during the subsequent sub-frame will be adjusted provided that the change in PWM duty
cycles happens 2 clock cycles plus 40 µs before the change of sub-frame (toggling on pin.SEL0/pin.SEL1). This is
defined as the time-out period.
The resolution of the PWM function is 8-bits: the M09000 is capable of resolving variations of 1/255 in the duty
cycle of the PWM signal of frequency in the range of 5 kHz to 20 kHz. If PWM input is low continuously the output
current will be forced to 1/255 of the full scale value.
To optimize power dissipation the headroom of each driver can be programmed using bits HEADROOM_x. To
achieve the specified accuracy the drivers require 10 mV of headroom for each 100 mA of current delivered to the
LED down to a minimum of 50 mV. This corresponds to a driver impedance of 100 mΩ.
For example, if the maximum current required in the system is 700 mA the headroom that must be programmed is
70 mV (0110 binary code). If the maximum current required in the system is 350 mA the headroom that can be
programmed is 40 mV (0011 binary code) but to achieve the specified accuracy 50 mV (0011 binary code) should
be used.
Because of the driver architecture, the current overshoot in the M09000 is maintained well below 10%.
The driver will issue an alarm at the pin.FAIL in case of open or shorted LED and in case the LED cathode is
shorted to ground.

Buck-boost Converter
The M09000 buck-boost converter controls the common anode voltage of the LED sub-assembly to guarantee
optimal system efficiency.
The M09000 automatically adjusts the anode voltage of the LED to guarantee enough headroom for the LED and
the driver to operate.
The typical current turn-on, limited by the DC-DC converter slewing is 30 µs with a transition of the LED anode
voltage from 2.5 V to 3.5 V. This is very well representative of a red to green LED transition which is usually the
slowest transition since the voltage difference between red and green LED is the highest.
The buck-boost converter is capable of delivering 1.2 A with a minimum battery voltage of 3.15 V (1 A at 2.7 V).
The maximum buck-boost output voltage is 4.6 V.
The M09000 has a programmable undervoltage lockout at register.ALARM_CTRL0.bit[7:6] and overvoltage
protection.
Moreover, a programmable current limiter (both positive and negative) allows the user to select the most
appropriate inductor characteristic for the specific application by trading off inductor area with series resistance.

the battery input relative to the buck-boost converter (pin.PVDDD) and the buck-boost converter output
(pin.PVOUT).
For each of the sub-frames (as defined by the status of SEL0 or SEL1, or SEL0, SEL1 and PWM, in case any of
INPUT_CONT pairs of bit [1:0], [3:2] or [5:4] is 11b) the ADC first converts the internal temperature sensor input
(junction temperature of M09000) then pin.PVDDD and finally pin.PVOUT and stores these values in the
corresponding registers at address 0x49h through 0x52h. The start conversion strobe is a change in the status of
the input pins (SEL0/1, PWM) and pin.PVOUT is converted last to allow time for it to settle. Since the slewing of the
DC-DC converter for a red to green translation is typically < 40 µs and the conversion rate of the ADC is 4 ksps, the
conversion of the PVOUT will start only 500 µs after the sub-frame starts guaranteeing that the PVOUT voltage is
in fact settled.
The PVDDD and PVOUT voltage data is stored in a separate register for each subframe (REG/GREEN/
BLUE_VLED/VBAT[9:0]), while the temperature information is stored in (TEMP[9:0]).
Since the conversion rate is 4 ksps the user should wait at least 750 µs after the subframe change before reading
back the digitized values for that subframe; alternatively the microcontroller can monitor the status bits to
determine if the conversion is completed.
The ADC can be setup in such a way that it continuously cycles between the three signals to be converted
regardless of the input pin (register.ADC_CONT.bit[1]=1). In that case the PVDDD and PVOUT conversion are
always stored in the registers corresponding to the red subframe.
The voltage accuracy of the ADC for the PVDDD and PVOUT is determined by the slope error (+/-5%) since the
offset error (+/-8 mV) will be insignificant for the voltages measured (>2 V). It should be noticed that the M09000
will measure internal PVDDD and PVOUT voltages: these may be up to 100 mV different (lower in the case of
PVDDD, higher in the case of PVOUT) than the external ones due to the IR drops on the pins and bondwires of the
M09000 itself.
Absolute accuracy of the temperature sensor is ±8 °C after calibration at room temperature.
The ambient temperature of the system can be calculated from the part junction temperature, the part power
dissipation and the package thermal resistance (θJA). This is highly dependent on the system characteristics. For
example, area and material of the board, number of routing versus ground layers, presence of heat sinks and other
mechanical factors, but a typical value for the M09000 is around 39 °C/W.
3.9
FAIL Pin
The FAIL is an active low open collector pin which will issue an alarm when abnormal operating conditions are
detected. The pin can function as a status pin or in interrupt mode. In status mode pin.FAIL will go low for the
duration of the internal alarm time which can be very short, while in interrupt mode the pin will generate a pulse of
programmable length. The mode and pulse duration can be set through register.FAIL_CTRL.bit[3:0].
In interrupt mode the pin will return high after the programmed duration even if the alarm is still present. In interrupt
mode pin.FAIL will toggle every time the status of one of the alarm pins changes. The mode and pulse duration can
be set through register.FAIL_CTRL.bit[3:0].

The external microcontroller can read back the content of registers 0x70h and 0x71h (ALARM0 and ALARM1) to
understand the cause of the alarm once pin.FAIL has triggered. The bits corresponding to the alarm in registers
0x70h and 0x71h remain high once an alarm is captured until the user clears the alarm registers via
register.FAIL_CONT.bit[7].
Any alarm bit can be masked by setting the corresponding bit in registers register.ALARM0_MASK.bit[7:0] and
register.ALARM1_MASK.bit[7:0].
The following abnormal situation can be detected by the M09000 and signaled through pin.FAIL and
register.ALARM0/register.ALARM1.
1. Any of the on board regulators not ready (register.ALARM0.bit[3:0]): the regulator is enabled but its output
voltage is lower then 90% of its programmed value. This generally is associated with a shorted output
condition. All of the on-board regulators are monitored:
- 2.5 V and 3.3 V LDOs
- 1.8 V and 1.0 V Buck converters
2. DMD supplies not ready register.ALARM0.bit[4]. At the enable of the LEDs (LED_ON=H), if the PRJ_ON=H,
the M09000 will monitor the status of the DMD supplies (V18, VHIGH, VMID, VNEG). If any of the supply
voltages is lower then 90% of the final value, an alarm will be issued.
3. Buck-boost current limit (register.ALARM0.bits[6:5]): These alarms signal a current limit situation in the buckboost converter.
4. Overtemperature (register.ALARM0.bit[7]): this alarm signals when the junction temperature of the part is
109 °C.
5. Undervoltage at any of following battery inputs (register.ALARM1.bit[0]):
- PVDD1
- PVDD2
- PVDDD
- PVDDM
Undervoltage alarm is generated when the input battery voltage is below a certain threshold. Programmed in
register.ALARM_CTRL0.bit[7:6]. If the battery voltage goes below 2.55 V the part will automatically reset.
6. Undervoltage at pin.PVOUT (register.ALARM1.bit[1]): since over-current condition may also happen in
situations other than the output voltage shorted to ground (for example current limiter set lower to prevent
saturation in the external inductor during transients) a separate undervoltage alarm is provided
(register.ALARM1.bit[0]). Please note that this alarm may also indicate a shorted LED. The threshold for this
alarm is set at 1.5 V
7. Overvoltage at pin.PVOUT (register.ALARM1.bit[4]): the M09000 monitors the output voltage in real-time and
issues an alarm if the output voltage exceeds 5.2 V.
8. LED alarm for 3 conditions:
- LED shorted: as previously described this is detected by the pin.PVOUT undervoltage alarm.
- LED open or LED cathode shorted to ground (register.ALARM1.bit[7:5]): this is detected when, while the
driver is ON, the voltage on the driver falls below 30 mV. The threshold can be programmed with

register.ALARM_CTRL0.bit[1:0]. With this circuitry the user can identify which LED is creating the issue by
reading register.ALARM1.bit[7:5]. Please note that the overvoltage alarm also may signal a LED open
condition.
It should be noticed that pin.FAIL may chatter during the start-up of the buck converter (6 ms) following
pin.MP_EN.
Also during thermal shutdown and undervoltage lockout pin.FAIL will be high: however, the part will signal an
overtemperature and undervoltage alarm before the thresholds of the RESET state.
3.10
Overtemperature and Thermal Shutdown
The overtemperature alarm makes use of the ADC to determine if the temperature of the part is at the maximum
operating limit. The threshold is set to 120 °C+/-8 °C. Please notice that the overtemperature alarm is functional
only when the LED_ON=H.
A thermal shutdown block is also present. This block will force the M09000 into disable mode if the internal junction
temperature reaches the thermal shutdown threshold (135 °C). This is to avoid permanent damage to the part. A
hysteresis of ~30 °C allows for the part to be enabled again when the temperature drops below ~105 °C. The part
registers must be re-written by the host after a thermal shutdown.
3.11
Programmable Serial Interface
The M09000 can be configured through an I2C interface (pins SDA/SCL). The maximum SCL supported is
400 kHz.
The 7-bit slave ID is 011 0110 (36h) resulting in 6Ch (for a write) and 6Dh (for a read).
4.7 kΩ pull up resistors should be used on the I2C pins.
3.12
OTP Programming
The M09000 internal OTP memory can be programmed by writing sequentially in the following registers: 0x31h,
0x32h and 0x33h the values AFh, FAh and 55h respectively. This will store in the OTP memory of the device the
content of register 0x13h through 0x16h. These values are now the default values for those registers therefore
when the M09000 powers up the current settings programmed will be loaded as defaults. This effectively allows to
store predefined current values in the part and can be used for storing white balance control information
During programming the I2C is disabled. After finishing programming the OTP memory, user can issue a soft_reset
by writing AAh to address 0x30 (or power cycle the device) to go back to the normal operating mode.

M09000-14
LED Driver and PMIC for DLP/LCOS Pico Projectors
Rev V2
In a DLP system it is expected that the DMD power is functional and the proper DMD voltages are available when
LED_ON=H. For this reason the part will issue an alarm if PRJ_ON=H, LED_ON=H but the outputs of the DMD are
not at the proper level. As any other alarm of the M09000, this alarm can be masked.
In any of these states, if the battery voltage drops below 2.55 V or the junction temperature reaches 135 °C, the
part will be reset. All registers are reset to the default state, the buck converters, LDOs, DMD power, and buckboost converter are disabled. The part will not be in the disabled state as long as MP_EN=H because the internal
voltage references, thermal shutdown and under voltage monitor are still enabled. If the supply rises above 2.65 V
the part will go back to the enabled state and the registers will need to be rewritten.

Disabled
Battery is connected to the part.
In case pin.MP_EN is also connected to the battery, supply ramp time must be > 500 µs; this can be
guaranteed using appropriately sized decoupling caps.
The part will return in this state in case of thermal shutdown. The part needs to be reset by lowering
pin.MP_EN.
In this mode of operation the part will consume typically < 5 µA.
RESET
The M09000 enters this mode of operation if the supply drops below 2.55 V or the junction temperature
reaches 135 °C. To exit from this mode, the battery voltage needs to be above 2.65 V and the internal junction
temperature must be below 102 °C.
In this mode of operation the part is in reset, the buck converters and LDOs are disabled. The only blocks
enabled are the references, the overtemperature protection and the undervoltage protection. During thermal
shutdown the undervoltage monitor (POR) will also be powered down.
Since the 1.8 V buck regulator generating the supply for the internal digital block is disabled, all the registers
content is lost and I2C communication is not possible.
PMIC Enabled
When pin.MP_EN=H all the buck converters and the LDOs are enabled generating the required voltages.
I2C communication with the part is possible after start-up period.
All the supplies will be available within 6 ms of the MP_EN=H signal assuming 4.7 µF capacitor is used for
decoupling for each one of them. Following start-up I2C communication is possible and the external
microcontroller can program the registers according to the user settings
Power dissipation in this state depends on the load on each of the generated supplies and on the battery
voltage. With no load on any of the supplies, the power dissipation in this state is typically 2.5 mA.
In this state the SEL1/SEL0/PWM pins activity will be disregarded.
DMD Power Enabled
In DLP applications, 0x0B(0)=1b (PRJ_ON=H) shouild be set high. The digital engine waits a minimum of
100 ms before generating a EMU_RST=H signal. The V18 boost generator will be enabled to generate +18 V
(V18) and the corresponding LDO generates VMID. Once VMID is ready the M09000 waits 10 msec before
generating VHIGH (using the associated LDO) and VNEG.
When 0x0B(0)=0b (PRJ_ON=L) or an alarm condition is issued. VHIGH and VNEG are discharged first and
within 12 msec the VMID is also discharged. The boost converter generating V18 is shut down last.
LED Enabled
When 0x1B(0)=1b (LED_ON=H), the M09000 enables the buck-boost converter. The LED common anode
voltage is kept at 3.7 V. Soft start for the buck-boost is
