This pin is the device digital ground connection for the 5.0 V and 2.5V logic. DGND,
LGND, and AGND are internally connected to PGND via a back to back diode.
Battery voltage sense input. This pin can be connected directly to the battery line for
voltage measurements. The voltage present at this input is scaled down by an
internal voltage divider, and can be routed to the internal ADC via the analog
multiplexer.The pin is self-protected against reverse battery connections. An
external resistor (RVSENXSE) is needed for protection
