MAX6864Nanopower µP Supervisory Circuits with Manual Reset and Watchdog Timer | Supervisors | 24 | Active | 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 VCCrises 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 theThreshold Suffix Guidein 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 theSelector Guidein 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.ApplicationsGlucose Monitors/Patient MonitorsMP3 Players/PagersPDAs and Cell PhonesPortable Battery-Powered Equipment |
