The MAX703CSA+ is a single-channel battery backup circuit supervisor from Analog Devices. The output is push-pull, totem-pole topology, so no external pull-up resistor is needed on the reset line. This simplifies the layout for a direct connection to the microcontroller reset input.
No pin-compatible second-source or official successor is recorded for this order code.
It also switches to a backup battery when the main supply drops, protecting SRAM or real-time clock data.
It provides an active-low reset output in a push-pull, totem-pole configuration. This means the reset line is driven high or low without needing an external pull-up resistor.
