Power Management (PMIC)

Measures battery charge, current, voltage, and temperature with an I2C interface.

Monitors up to 18 series battery cells and communicates through an isolated isoSPI daisy chain.

Debounces a pushbutton and provides latched on/off control, interrupt signaling, and a battery-preserving freshness-seal mode.

Serially controls multiplexed seven-segment displays or individual lamps, supporting five digits or up to 25 LEDs.
