Ultra Flexible Power Sequencer

The ultra-flexible power sequencer takes care of the complete platform start-up, state-transitioning and power down

procedure.TheMYXPM6021operatesautonomouslyandreducesthepowerconsumptionwhenenteringstand-byor

Auxiliary Function

An analogue to digital converter (ADC) with 10-bit resolution combined with a multi-channel input multiplexer allows

measurement of the input supply voltage, battery ID, PMIC die temperature, as well as 5 battery pack and system

temperatures.Thenumberofexternalcomponentsissignificantlyreducedduetotheintegrationof16GPIO’s,3channel
