Pinout and package

5 Pin Configuration and Functi… — Package: **SOT-5X3 (DRL), 8-Pin SOT, 2.1 mm × 1.6 mm**

Pin	Name	Function	Source
1		GND, Device ground
2		VOUT, Output power
3		VIN1, Channel 1 input power
4		ON, Active low enable pin. Device is enabled when ON is pulled low and the device turns off both channels when ON is pulled high.
5		GND, Device ground
6		VIN2, Channel 2 input power
7		VOUT, Output power
8		ST, Status pin. Pulled high when VIN1 is being used and pulled low when VIN2 is being used. Can be pulled up to VIN1 to reduce quiescent current when VIN2 is powering the output.
