Power Module

The IC of the Power Management Module is the LTC2942. The module measures battery charge state, battery voltage and chip temperature in handheld PC and portable product applications. The power management module has I2C connectivity with the MCU for monitoring the state of the battery. The module provides regulated power from the battery to the rest of the hardware modules. This module integrates a Low Drop-Out (LDO) to supply a single fixed 3.3 V power rail.
