MMPF0100 VGEN4 1.8V

sylvia — Thu, 04 Jun 2015 07:35:30 GMT

Hi Community

We had received Default Configuration of MMPF0100, The default voltage at VGEN4 is not got. All other regulator outputs are proper.

Kindly suggest what may be the issue. The input to PMIC (VIN) is 3.4V. If suppose we power up the PMIC through Battery , the input Voltage will go upto 4.2 V.

Is there any proplem for the regulators, since VGEN4 Input regulator VIN max is 3.6 V???

Thanks and Regards

Sylvia

Please check Your design regarding the Startup erratum

(False start and/or non-start of regulators).
