It tracks two independent voltage rails with a threshold of 2.31 V on one channel and an adjustable threshold on the second, issuing an active-low reset when either rail drops below its trip point. The open-drain output stays asserted for a minimum of 140 ms after all monitored voltages rise above threshold, giving the downstream processor time to stabilise before release. Rated for -40°C to 125°C ambient, this monitor suits industrial and automotive environments where the board sees wide thermal swings. ## Active production, no cross-reference on record The MAX6389XS23D3+ carries an active lifecycle status — the manufacturer continues to support new orders through authorised channels. No official second-source or pin-compatible successor is listed; the BOM line depends on this specific Maxim order code.","metaTitle":"MAX6389XS23D3+ Power Supply Monitor, SC-70-4, Active Low","metaDescription":"MAX6389XS23D3+ power supply monitor, SC-70-4, monitors 2 voltages, 2.31V threshold, 140ms reset timeout, -40°C to 125°C.
