Description

The MAX6966ATE+T is an electronic component model from the LED Drivers product category. It is a supervisory circuit that simplifies power-supply monitoring and battery-control functions in microprocessor (μP) systems. This model reduces the complexity and number of components required for the functions mentioned above which include μP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning. MAX696/MAX697 significantly improve system reliability and accuracy compared to that obtained with separate ICs or discrete components.
