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 KΩ 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.
