Table 5-1 Pin Functions
PIN I/O DESCRIPTION
NAME NO.
GND 1 - Device ground.
VOUT 2, 7 O Output power.
VIN1 3 I Channel 1 input power.
PR1 4 I Selects between VIN1 and VIN2. When PR1 is high VIN1 is selected, and when PR1 is low VIN2 is selected.
MODE 5 I Device is put into Priority mode when MODE is tied to VIN1 and manual mode when MODE is pulled up to an external voltage.
VIN2 6 I Channel 2 input power.
ST 8 O Open drain status pin. Pulled low when VIN1 is not being used.
