Description

The WM835x series of PMICs include an AUXADC which can be used tomonitor a range of system operating parameters, including the voltagesof the major supplies within the system. Currently the driver providessimple access to these major supplies.

Voltage Monitoring

Voltages are sampled by a 12 bit ADC. For the internal supplies the ADCis referenced to the system VRTC.
