Reset supervisor for industrial and automotive rails
It monitors one supply voltage and asserts an active-low reset signal when the monitored voltage falls below a threshold, holding the reset for a typical 50µs timeout after the supply recovers. The output is open-drain, making it suitable for wired-OR connections with other reset sources. The threshold is adjustable or selectable via external resistors, so one part number can cover multiple rail voltages across a BOM.
