Description

The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–MAX6869 ultra-low-current (170nA, typ) microprocessor (µP) supervisory circuits combine voltage monitoring, watchdog timer, and manual reset input functions in a 5-pin SOT23 package. These devices assert a reset signal whenever the monitored voltage drops below the factory-trimmed 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 100mV increments (see the Threshold Suffix Guide in the full data sheet). 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 in the full data sheet). The MAX6854/MAX6855/MAX6856/MAX6861–MAX6869 provide a manual reset input, MR-bar. 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.
