It monitors up to three supply rails against a 3.3V threshold and asserts an active-low, open-drain reset output when any monitored voltage falls below the threshold. The reset timeout is selectable among 10 ms, 20 ms, or 50 ms minimum durations, giving the designer flexibility to match downstream reset hold requirements. This part is built for industrial environments — the operating temperature range spans -40°C to 85°C, covering factory automation, outdoor telecom cabinets, and engine-bay electronics where thermal cycling is routine. The open-drain output allows multiple reset sources to be wire-ORed on a shared reset line, a common topology in multi-rail systems where a single fault should pull the entire system into reset. ## Active production — no LTB watch needed The DS1830AS+ carries an active lifecycle status with ROHS3 compliance. There is no last-time-buy window, no NRND flag, and no announced end-of-life. For a BOM freeze or a new design, this part does not introduce obsolescence risk. ## What the 3.3V threshold and three-channel count mean for the BOM The selectable timeout (10/20/50 ms) lets you tune the reset pulse width to the slowest rail's rise time without adding external capacitors.","metaTitle":"DS1830AS+ Maxim Integrated Sequencer, 3-Channel Supervisor","metaDescription":"Maxim Integrated DS1830AS+ is a 3-channel voltage sequencer with active-low open-drain reset, 3.3V threshold, industrial temp -40°C to 85°C.
