The PF5024 provides a complete set of registers for control and diagnostics of the PMIC

operation. The configuration of the device is done at two different levels.

At first level, the OTP mirror registers provide the default hardware and software

configuration for the PMIC upon power up. These are one-time programmable and

should be defined during the system development phase, and are not meant to be

modified during the application. See Section 17 "OTP/TBB and hardwire default

configurations" for the OTP configuration feature.

At a second level, the PF5024 provides a set of functional registers intended for

system configuration and diagnostics during the system operation. These registers are

accessible during the system On state and can be modified at any time by the system

control unit.

The device ID register provides general information about the PMIC:

• DEVICE_FAM[3:0]: indicates the PF50x0 family of devices.

0101 (fixed)

• DEVICE_ID[3:0]: provides the device type identifier

0100 = PF5024 QM

1100 = PF5024 ASIL B

Registers 0x02 and 0x03 provide a customizable program ID registers to identify the

specific OTP configuration programmed in the part.
