●Serial Interface
1. SPI format
・When IFMODE is set to “H”, it can interface with SPI format.
・The serial interface is four terminals (serial clock terminal (SCL), serial data input terminal (SDA), and chip
selection input terminal (CE)).
(1)Write operation
・Data is taken into an internal shift register with rising edge of CLK. (Max of the frequency is 13MHz.)
・The receive data becomes enable in the “H” section of CE. (Active “H”.)
・The transmit data is forwarded (with MSB-First) in the order of write command “0”(1bit), the control register address
(7bit) and data (8bit).

(2) Bit Transfer
SCL transfers 1-bit data during H. During H of SCL, SDA cannot be changed at the time of bit transfer. If SDA changes
while SCL is H, START conditions or STOP conditions will occur and it will be interpreted as a control signal.

Fig.6 Bit transfer (I2C format)
(3) START and STOP condition
When SDA and SCL are H, data is not transferred on the I2C- bus. This condition indicates, if SDA changes from H to L
while SCL has been H, it will become START (S) conditions, and an access start, if SDA changes from L to H while SCL
has been H, it will become STOP (P) conditions and an access end.

(5) Writing protocol
A register address is transferred by the next 1 byte that transferred the slave address and the write-in command. The
3rd byte writes data in the internal register written in by the 2nd byte, and after 4th byte or, the increment of register
address is carried out automatically. However, when a register address turns into the last address (77h), it is set to 00h
by the next transmission. After the transmission end, the increment of the address is carried out.

The LED little light up by SW pin’s parastic capacitance maybe that it depends on LED’s sensitivity of current though
LED current setting is 0mA.
It improves this problem that the register (reference value: 1MΩ) is set up between SW pin and GND pin.

●Notes for use
(1) Absolute Maximum Ratings
An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can
break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any
special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety
measures including the use of fuses, etc.
(2) Power supply and ground line
Design PCB pattern to provide low impedance for the wiring between the power supply and the ground lines. Pay attention
to the interference by common impedance of layout pattern when there are plural power supplies and ground lines.
Especially, when there are ground pattern for small signal and ground pattern for large current included the external
circuits, please separate each ground pattern. Furthermore, for all power supply pins to ICs, mount a capacitor between
the power supply and the ground pin. At the same time, in order to use a capacitor, thoroughly check to be sure the
characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low
temperature, thus determining the constant.
(3) Ground voltage
Make setting of the potential of the ground pin so that it will be maintained at the minimum in any operating state.
Furthermore, check to be sure no pins are at a potential lower than the ground voltage including an actual electric
transient.
(4) Short circuit between pins and erroneous mounting
In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can
break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between pins or between the pin
and the power supply or the ground pin, the ICs can break down.
(5) Operation in strong electromagnetic field
Be noted that using ICs in the strong electromagnetic field can malfunction them.
(6) Input pins
In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the
parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the
input pin. Therefore, pay thorough attention not to handle the input pins, such as to apply to the input pins a voltage lower
than the ground respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input
pins when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to
the input pins a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics.
(7) External capacitor
In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a
degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc.
(8) Thermal shutdown circuit (TSD)
This LSI builds in a thermal shutdown (TSD) circuit. When junction temperatures become detection temperature or higher,
the thermal shutdown circuit operates and turns a switch OFF. The thermal shutdown circuit, which is aimed at isolating
the LSI from thermal runaway as much as possible, is not aimed at the protection or guarantee of the LSI. Therefore, do
not continuously use the LSI with this circuit operating or use the LSI assuming its operation.
(9) Thermal design
Perform thermal design in which there are adequate margins by taking into account the permissible dissipation (Pd) in
actual states of use.
(10) About the pin for the test, the un-use pin
Prevent a problem from being in the pin for the test and the un-use pin under the state of actual use. Please refer to a
function manual and an application notebook. And, as for the pin that doesn't specially have an explanation, ask our
company person in charge.
(11) About the rush current
For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal
powering sequence and delays. Therefore, give special consideration to power coupling capacitance, power wiring, width
of ground wiring, and routing of wiring.
(12) About the function description or application note or more.
The function description and the application notebook are the design materials to design a set. So, the contents of the
materials aren't always guaranteed. Please design application by having fully examination and evaluation include the
external elements.
(13) SW1-7 don’t have short protection.
When need protection, please use fuse element.
