What the 4.65 V threshold means for your rail
The MAX703ESA+ is a single-channel battery backup supervisor IC from Analog Devices, monitoring a single voltage rail with a 4.65 V threshold. The output is totem-pole, so it drives high or low without a floating state.
Package and board-fit for the 8-SOIC footprint
The device monitors a single voltage rail, so the board layout is straightforward: the VCC pin connects to the monitored supply, the GND pin to the system ground, and the RESET pin to the processor's reset input. No external timing capacitor is needed for the 140 ms timeout — it is generated internally.
