The Analog Devices MAX16058ATA17+T is a simple reset/power-on reset IC that monitors a single supply rail and asserts a reset signal when the voltage drops below the threshold. The reset output is active-low, open-drain, so it can be wire-ORed with other reset sources or pulled up to a different logic voltage. The threshold is fixed at 1.665V, which suits low-voltage core rails — think 1.8V or 1.5V supplies in FPGAs, SoCs, or DSPs where a 1.665V trip point catches a brownout before the logic glitches. The reset timeout is adjustable via an external capacitor, giving you control over the hold-off period after the supply recovers.
