Power Manager and Sleep Mode

Overview

The power manager ensures the reliable and efficient operation of various power functions. The power manager
controls the internal switched supply domains during the full sequence of power states so that the device powers
up and down smoothly. During power-up, the power manager guards the device until the internal supplies have
been validated and the digital core assumes normal operations. In all power modes, the power manager monitors
power supplies for under- and over-voltage conditions. In Sleep mode, the power manager minimizes current
consumption and can quickly restore device configurations after waking up.

Device Power Operation

The power manager block minimizes required user interaction while providing extensive diagnostic indicators.
Power manager status registers can be polled for valid supply levels, and a system-level interrupt (ERRB=0) can be
generated in the case of a device power failure.
MAX96752 uses power rails (V
Note: If the power manager sends an ERRB interrupt due to a power fail condition, check PWR0, PWR1, and other
diagnostic registers to identify the source of the failure. Refer to the voltage monitoring section of the respective
data sheet for additional details.
