5.1

Functional state machine

Overview

STPMIC25 integrates advanced low power features controlled by the application processor through I²C, six

digital control pins (PONKEYn, WAKEUPn, PWRCTRL1/2/3, and RSTn) and one interrupt output line (INTn).

The main parameter settings can be programmed in a non-volatile memory (NVM) as default values at the startup

time. See Section 5.5.2

All regulators can be independently controlled from the PWRCTRLx pins. This allows flexible configuration and a

fast transition between different power strategies at the application level.

Other features are provided to fulfill high-end application processors and advanced operating system needs:

•

Multiple turn-on/turn-off conditions

•

Mask_reset and restart_request options

•

Overcurrent and overvoltage protection

•

Thermal protection

•

Watchdog

•

Interrupt controller

•

Safety management

•
