MAX6862 Datasheet | Maxim Integrated

Description The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860- MAX6869 ultra-low-current (170n A, typ) microprocessor (µP) supervisory circuits bine voltage monitoring, watchdog timer, and manual reset input functions in a 5pin SOT23 package. These devices assert a reset signal whenever the monitored voltage drops below the factorytrimmed reset threshold voltage, manual reset is asserted, or the watchdog timer expires. The reset output remains asserted for a minimum timeout period after VCC rises above the reset threshold and manual reset is deasserted. Factory-trimmed reset threshold voltages are offered from +1.575V to +4.625V in approximately 100m V increments (see Threshold Suffix Guide). Each device is offered with six minimum reset timeout options, ranging from 10ms to 1200ms. The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860- MAX6869 are offered in a variety of configurations (see the Selector Guide). The MAX6854/MAX6855/MAX6856/ MAX6861- MAX6869 provide a manual reset input, MR. The MAX6864- MAX6869 offer a watchdog timer that monitors activity at the WDI input to prevent code execution errors. The MAX6864- MAX6869 offer watchdog timeout options of 3.3s or 209s (typ). The MAX6861/ MAX6862/MAX6863 feature a pin-selectable reset delay period of 10ms or 150ms (min). Push-pull active-low, push-pull active-high, and open-drain active-low reset outputs are available.
