Dual-voltage watchdog in a small footprint
The MAX6707YKA is a multi-voltage supervisor from Analog Devices that monitors two supply rails and asserts a reset signal when either falls below its threshold. It's built for systems that need to keep track of both a main core voltage and an I/O or auxiliary rail, all in a SOT-23-8 package that fits tight PCB layouts.
140 ms reset timeout and wide temperature range
A minimum 140 ms reset timeout holds the system in reset long enough for all supplies to stabilise after a brown-out or power-up event, preventing premature start-up that could cause logic glitches.
