Programs the overhead voltage between the peak negative ringing level and VBATH.
This value increases or decreases as the battery voltage changes in order to maintain a
constant open circuit voltage but maintains its user-defined setting to ensure sufficient
overhead for audio transmission when the battery voltage decreases. 0 to 63.3 V pro-
grammable range, 4.907 mV/LSB, 1.005 V effective resolution.
Scaled TIP Voltage Measurement.
Reflects the TIP to ground voltage measured through the monitor ADC.
4.92 mV/LSB, 2’s complement. 0 to 160.173 V range, 4.907 mV/LSB, 628 mV effective
resolution (251 mV effective resolution for VTIP < 64.07 V). Updated at 800 Hz rate,
2’s complement.
Scaled RING Voltage Measurement.
Reflects the RING-to-ground voltage measured through the monitor ADC. 0 to
160.173 V range, 4.907 mV/LSB, 628 mV effective resolution (251 mV effective reso-
lution for VRING < 64.07 V). Updated at 800 Hz rate, 2’s complement.
