When the monitored voltage falls below threshold, the reset output (Active Low, open-drain) asserts and holds for a minimum of 140 ms after the supply recovers, giving the downstream processor time to stabilize before it releases the reset line. Housed in an 8-uDFN (2x2 mm) package, the part fits into compact battery-backed SRAM or RTC circuits where board space is tight and the backup switchover must be glitch-free.","metaTitle":"MAX16039PLA29+T Battery Backup Circuit, 2.93V Threshold","metaDescription":"MAX16039PLA29+T Battery Backup Circuit from Analog Devices.
