READY
The logic high state on READY output indicates that the nPM6001 EK has started successfully and is ready for use. This is an open-drain type pin.
N_INT
The N_INT signal is an active low, open drain pin that provides interrupt signals to the host. It is configured, read, and cleared through the Two-Wire Interface (TWI). See the nPM6001 Product Specification for more information.
GPIOs GPIO0, GPIO1, and GPIO2 are GPIOs available for use by the host.
Enable (EN)
This pin controls the output state of the PMIC (ON/OFF). In a static configuration, the EN pin can be connected to VIN (ON) or GND (OFF) with a jumper. Alternatively, it can be connected to a host device or a PGOOD pin of a PMIC higher in the chain for power sequencing or another controlling circuit.
BUCK mode selection BUCK_MODE0, BUCK_MODE1, and BUCK_MODE2 input pins are a fast control method to toggle the power mode of the buck regulators.
