The MAX6305UK00D2+T is a multi-voltage supervisor from Analog Devices that monitors two supply rails and asserts a reset signal when either falls below its threshold. The voltage threshold is adjustable/selectable via external resistors, giving the designer flexibility to set the trip point for each monitored rail independently rather than being locked into a fixed factory trim. The reset timeout is a minimum of 20 ms, which holds the reset line low long enough for the downstream processor's oscillator and PLL to stabilise after the supply rails are within tolerance.
Package, footprint, and temperature grade
The small body (roughly 2.9 mm x 1.6 mm) suits space-constrained layouts on multi-layer boards where the supervisor sits close to the monitored processor or ASIC. For industrial or automotive environments, a wider-temperature variant from the MAX6305 family would be needed.
