iMX6 PF0100 PMIC

Hi,

I have a problem with a coin cell battery consumption. Also on power-off board, on battery we have a current like 400 uA.

How can configure the PMIC chip to reduce the current to 4-7 uA?
How can configure the PMIC to use a rechargeable battery?

Thanks

Antonio

Hi Antonio

power consumption may be caused by pull loads

connected to pins, powered from SNVS power domain,

like BOOT_MODE0,1, ONOFF,PMIC_ON_REQ,PMIC_STBY_REQ,

POR, TAMPER. Table 8. Maximum Supply Currents IMX6DQCEC

shows max.VDD_SNVS_IN current as 275uA.. PMIC charger is described in

MMPF0100 sect.6.4.7.1 Coin Cell Charger Control, PMIC standalone

power consumption in Table 9. Current Consumption Summary.

Best regards

igor
