The /PG/GPO pin is an open-drain output that by default indicates when a valid IN supply is present. It can also be configured to be a general purpose output (GPO) controlled through I2C. Connect /PG/GPO to the desired logic voltage rail using a 1-kΩ to 100-kΩ resistor, or use with an LED for visual indication.
Below is the description for each configuration:
In its default state, /PG/GPO pulls to GND when the following conditions are met: VIN > VIN_UVLO, VIN > VBAT+VSLEEP and VIN < VIN_OVP. /PG/GPO is high impedance when the input power is not within specified limits. PG_Mode is set to b0 to indicate the state of VIN.
General purpose open drain output when setting the PG_MODE bits to b1. The state of the /PG/GPO pin is then controlled through the PG_GPO bit, where if GPO_PG is 0 , the /PG/GPO pin is high impedance and if it is 1, the /PG/GPO pin is low.
