2.925V threshold, 1.2s timeout — the reset supervisor for a single supply rail
The MAX6858UK29D4+ is a single-channel simple reset/power-on reset IC from Analog Devices, monitoring one voltage rail with a 2.925V threshold and asserting an active-low, push-pull output when the supply dips below that level. The reset output remains asserted for a minimum of 1.2 seconds after the supply recovers above the threshold, providing a clean power-on delay before the downstream processor or logic starts executing.
