■
*$3*&)7
The L99MD02 IC is a 6 x half bridge driver for
automotive applications. The device is intended to
drive DC-motors. It is possible to drive 3
DC-motors simultaneously or up to 5 DC-motors
sequentially.
The integrated 24 bit standard serial peripheral
interface (SPI) controls all outputs and provides
diagnostic information: normal operation,
open-load in on-state, overcurrent, temperature
warning and overtemperature.

Overview
2.1
Power supply: VCC
The supply voltage VCC (3.3 V / 5 V) supplies the whole device. In case of power-on (VCC
increases from undervoltage to VPOR OFF = 2.75 V, typical) the circuit is initialized by an
internally generated power-on reset (POR). If the voltage VCC decreases under the
minimum threshold (VPOR ON = 2.55 V, typical), the outputs are switched off in 3-state (high
impedance). The status registers are cleared and the control registers are reset to their
default.

Power supply: VSA, VSB
Each VSA and VSB supplies the half bridges independently.
VSA → Out 1 to Out 3
VSB → Out 4 to Out 6
2.3
Standby mode
The standby mode of the L99MD02 is activated by EN pin to low. The inputs and outputs are
switched off. The status registers are cleared and the control registers are reset to their
default values.
In the standby mode the current consumption is typically 5 µA.

L99MD02
PWM mode
PWM frequency typ. 100 Hz.
Duty cycle (SPI 2bit): 15%, 30%, 45% and 60%.
Each half-bridge is independently addressable (SPI 8bit).
2.5
Current monitor
The current monitor output sources a current image at the current monitor output which has
a programmable ratio (1/250, 1/500, 1/750, 1/1000) of the instantaneous current of the
selected half bridge (high side or low side). Via SPI it can be programmed which of the
outputs will be multiplexed to the current monitor output.
The current monitor output allows a more precise analysis of the actual state of the load
rather than the detection of an open-or overload condition. For example this can be used to
detect the motor state (starting, free-running, stalled).
2.6
Inductive loads
Each half bridge is built by an internally connected high-side and a low-side power DMOS
transistor. Due to the built-in reverse diodes of the output transistors, inductive loads can be
driven at the outputs
2.7
Diagnostic functions
All diagnostic functions (over/open-load, temperature warning and thermal shutdown,
over/undervoltage) are internally filtered and the condition has to be valid for at least 32 µs
(open-load: typ. 2 ms, respectively) before the corresponding status bit in the status
registers will be set. The filters are used to improve the noise immunity of the device. Openload and temperature warning function are intended for information purpose and will not
change the state of the output drivers. On contrary, the overload and thermal shutdown
condition will disable the corresponding driver (overload) or all drivers (thermal shutdown),
respectively. The microcontroller has to clear the overcurrent status bit to reactivate the
corresponding driver.
2.8
Temperature warning and thermal shutdown
If the junction temperature rises above Tj TW ON a temperature warning flag is set and is
detectable via the SPI. If the junction temperature increases above the second threshold
Tj SD ON, the thermal shutdown bit will be set and power DMOS transistors of all output
stages are switched off to protect the device. Temperature warning flag and thermal
shutdown bits are latched. In order to reactivate the output stages, the junction temperature
must decrease below Tj SD ON - Tj SD HYS and the thermal shutdown bit has to be cleared by
the microcontroller.

Open-load detection
The open-load detection monitors the load current in each activated output stage. If the load
current is below the open-load detection threshold for at least 2 ms (tdOL) the corresponding
open-load bit is set in the status register.
Due to mechanical/electrical inertia of typical loads a short activation of the outputs (e.g.
3 ms) can be used to test the open-load status without changing the mechanical/ electrical
state of the loads.
2.11
Overload detection
In case of an overcurrent condition, a flag is set in the corresponding status register. If the
overcurrent signal is valid for at least tISC = 32 µs, the overcurrent flag is set and the
corresponding switch is switched off to reduce the power dissipation and to protect the
integrated circuit. The microcontroller has to clear the status bit to reactivate the
corresponding driver.
2.12
Cross-current protection
The device is cross-current protected by an internal delay time. If one driver (LS or HS) is
turned-off the activation of the other driver of the same half bridge will be automatically
delayed by the cross-current protection time. After the cross-current protection time is
expired the slew-rate limited switch-off phase of the driver will be changed to a fast turn-off
phase and the opposite driver is turned-on with slew-rate limitation. Due to this behavior it is

always guaranteed that the previously activated driver is totally turned-off before the
opposite driver will start to conduct. If wrong SPI commands try to turn-on both driver (LS
and HS) simultaneously, the high side and the low side will be (or stay) deactivated (3state).

Half bridge-output: the output is built by a high-side and a low-side
switch, which are internally connected. The output stage of both
switches is a power DMOS transistor. Each driver has an internal
parasitic reverse diode (bulk-drain-diode: high-side driver from output
to VSx, low-side driver from PGND to output).

VCC
Logic voltage supply 3.3V / 5V for this input a ceramic capacitor as
close as possible to GND is recommended
VSA
Power supply voltage for OUT 1 to 3 (external reverse protection
required): for this input a ceramic capacitor as close as possible to
GND is recommended. Important: For the capability of driving the full
current at the outputs all pins of VSA must be externally connected!
14, 15, 22
VSB
Power supply voltage for OUT 4 to 6 (external reverse protection
required): for this input a ceramic capacitor as close as possible to
GND is recommended. Important: For the capability of driving the full
current at the outputs all pins of VSB must be externally connected!

DI
SPI data in the input requires CMOS logic levels and receives serial
data from the microcontroller. The data is a 24 bit control word and the
most significant bit (MSB) is transferred first.
26
DO
SPI data out the diagnosis data is available via the SPI and this 3state output. The output will remain in 3-state, if the chip is not
selected by the input CSN (CSN = high)
24
CSN
SPI CSN chip select not (active low) this input is low active and
requires CMOS logic levels. The serial data transfer between the
L99MD02 and micro controller is enabled by pulling the input CSN to
low level.
30
SCK
SPI serial clock input this input controls the internal shift register of the
SPI and requires CMOS logic levels.
