Definition
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.
These are parallel input pins. These pins have internal 25 µA active pull-downs.
Each pin is one channel's drain, sinking current for the respective load.
Ground continuity is required for the outputs to turn on.
This pin is connected to battery voltage. A decoupling capacitor is required from
V_PWR to ground.
The MODE pin is connected to the MODE pin of the control IC. This pin has an internal
active 25 µA pull-up.
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.
