STANDBY PIN FOR PF3001

umasundaram — Fri, 18 Nov 2016 05:26:40 GMT

We are designing a handheld device with iMX6UL processor.The processor and peripherals are powered by the PMIC PF3001(MC32PF3001A7EP).

According to the pin-out diagram of PF3001 datasheet ,there is no standby pin in the PMIC.

But the "PF3001 simplified application diagram" (Figure1 on page1) of the PMIC datasheet ,shows a standby pin on PMIC,being controlled by the processor.(Figure attached below).

Can you please clarify the below doubts.

Q1. Is standby pin (or any equivalent pin) available on PMIC, MC32PF3001A7EP.

Q2. If the standby pin is not available,how can we bring the PMIC to standby.

Hi,

You can review the PF3000/PF3001 web pages -

12-Channel Configurable PMIC|NXP

PF3001 | 10-Channel Configurable PMIC|NXP

Taken from the PF3001 page -

If you want STANDBY / low power options you should use the PF3000, the PF3001 does not support STANDBY, its a simplified version of PF3000, for always ON applications.

I have feedback the documentation error to the PMIC support team, I would assume the PF3001 datasheet was created from the PF3000 and unfortunately the STANDBY pin on the block diagram was not removed.

Regards

Ross

We confirm that PF3001 does not have STANDBY pin, it does not support STANDBY function, it's a simplified version of PF3000, for always ON applications. The datasheet will be updated. Thanks.

Q1. Is standby pin (or any equivalent pin) available on PMIC, MC32PF3001A7EP.

A1. No, it doesn't have the Standby pin.

Q2. If the standby pin is not available,how can we bring the PMIC to standby.

A2. The PF3001 PMIC does not support the Standby mode. If the Standby mode is required, the PF3000 PMIC should be used instead.

Have a great day,
Artur
