General Description
The MAX6876 EEPROM-configurable, multivoltage power tracker/supervisor monitors four system voltages and ensures proper power-up and power-down conditions for systems requiring voltage tracking and/or sequencing. The MAX6876 provides a highly configurable solution as key thresholds and timing parameters are programmed through an I2C interface and these values are stored in internal EEPROM. The MAX6876 also provides supervisory functions and an overcurrent detection circuit.
