FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

VGEN1DRV

Drive output for the VGEN1 external PNP transistor.

VGEN1

Output of general purpose 1 regulator.

VGEN2DRV

Drive output for the VGEN2 external PNP transistor.

VGEN2

Output of general purpose 2 regulator.

VINGEN3DRV

1. Input for the VGEN3 regulator when no external PNP transistor used. Typically connected to BP.

2. Drive output for VGEN3 in case an external PNP transistor is used on the application. In this case, this pin must be

connected the base of the PNP transistor.

VGEN3

Output of general purpose 3 regulator.

VSRTC

Output regulator for the SRTC module on the processor. The VSRTC regulator provides the CLK32KMCU output level (1.2 V).

Additionally, it is used to bias the Low Power SRTC domain of the SRTC module integrated on certain FSL processors.

GNDREG1

Ground for regulators 1.

GNDREG2

Ground for regulators 2.

GNDREG3

Ground for regulators 3.

GENERAL OUTPUTS

GPO1

General purpose output 1. Intended to be used for battery thermistor biasing. In this case, connect a 10 K

Ω resistor from GPO1

to ADIN5, and one from ADIN5 to GND.

GPO2

General purpose output 2.

GPO3

General purpose output 3.

GPO4

General purpose output 4. It can be configured for a muxed connection into Channel 7 of the GP ADC.
