Definition
This pin is connected to battery voltage. A decoupling cap is required from V
PWR
to
ground.
These input pins control two output channels each when the
MODE
pin is pulled high.
These pins may be connected to pulse width modulated (PWM) outputs of the control
IC while the
MODE
pin is high. The states of these pins are ignored during normal
operation (
MODE
pin low) and override the normal inputs (serial or parallel) when the
MODE
pin is high. These pins have internal active 25
μA
pull-downs.
The
MODE
pin is connected to the
MODE
pin of the control IC. This pin has an internal
active 25
μA
pull-up.
These are parallel control input pins. These pins have internal 25
μA
active pull-
downs.

Each pin is one channel's drain, sinking current for the respective load.
No Connect
Serial Input
Not connected.
The Serial Input pin is connected to the SPI Serial Data Output pin of the control IC
from where it receives output command data. This input has an internal active 25
μA
pull-down and requires CMOS logic levels.
