Supervisor IC for battery-backed systems
The MAX6363PUT26 is a single-channel battery backup circuit from Analog Devices, packaged in SOT-23-6.
Threshold, timeout, and output behaviour
The 2.63 V threshold suits 3 V or 3.3 V rails where the supervisor must trip before the downstream logic enters an undefined state. The 150 ms minimum reset timeout ensures the supply and oscillator have stabilised before the processor starts executing code — long enough for most ceramic-cap decoupled rails to settle after a brownout.
Temperature grade and board integration
The SOT-23-6 footprint is a standard small-outline package that routes easily on two-layer boards. The single monitored channel keeps the BOM count low for designs that only need to watch the main supply rail.
