The open-drain, active-low output connects directly to the reset input of most MCUs, MPUs, or FPGAs without needing a level shifter. With the industrial temperature range of -40°C to +85°C, this part suits outdoor telecom gear, factory automation controllers, and power-supply sequencing circuits where a compact SOT-23-3 footprint matters. ## Threshold and timeout — the two numbers that decide fit The 3V threshold is the trip point at which the supervisor asserts reset. If your processor runs on a 3.3V rail, this part triggers when the supply drops to 3V — that gives 300mV of headroom before the core loses logic state, which is tight but workable for a cleanly regulated rail. For a 3.0V rail, the threshold is effectively the supply itself, so the supervisor holds reset until the rail is fully up. The 100ms minimum reset timeout holds the processor off long enough for the oscillator to stabilise and the supply to settle after power-up or a brown-out event. If your processor needs a longer reset pulse, you add an external RC delay on the output — the open-drain output makes that straightforward. ## Lifecycle and sourcing — active, no LTB watch needed ROHS3 compliant. For BOM-line planning, this part is a safe choice for new designs and ongoing production — no last-time-buy risk to schedule around.","metaTitle":"MAX6328UR30+T Simple Reset/Power-On Reset, 3V Threshold","metaDescription":"MAX6328UR30+T is an active-low, open-drain reset IC with 3V threshold and 100ms minimum timeout.
