PIN TYPE(1) DESCRIPTION
NAME YBH DSD
OUT0 A1 8 O Output 0 which contains current sink 0 and high-side scan FET 0. If not used, this pin must be floating.
GND A2

Thermal

Pad

 G Ground. Must be connected to the common ground plane
VCC A3 1 P Boost converter output. A 22 uF capacitor is recommended to be connected between this pin with GND and be placed as close to the device as possible.
OUT1 B1 7 O Output 1 which contains current sink 1 and high-side scan FET 1. If not used, this pin must be floating.
SYNC B2 2 I/O Synchronous between multiple devices. If not used, this pin can be connected to ground to save power.
SCL B3 3 I I2C serial interface clock input.
OUT2 C1 6 O Output 2 which contains current sink 2 and high-side scan FET 2. If not used, this pin must be floating.
OUT3 C2 5 O Output 3 which contains current sink 3 and high-side scan FET 3. If not used, this pin must be floating.
SDA C3 4 I/O I2C serial interface data input/output.
(1) P: Power Pin; I: Input Pin; I/O: Input/Output Pin; O: Output Pin.
