MAX6358

MAX6351–MAX6360 Dual/Triple-Voltage μP Supervisory Circuits General Description The MAX6351–MAX6360 microprocessor (μP) supervisors with multiple reset voltages significantly improve system reliability and accuracy compared to separate ICs or discrete components. If any input supply voltage drops below its associated preset threshold, all reset outputs are asserted. In addition, the outputs are valid as long as either input supply voltage remains greater than +1.0V. All devices in this series have an active-low debounced manual-reset input. In addition, the MAX6358/MAX6359/ MAX6360 offer a watchdog timer input with a 46.4s startup timeout period and a 2.9s timeout period. The MAX6355/ MAX6356/MAX6357 offer an additional voltage-monitor input to monitor a third voltage. The MAX6351 features two active-low, push-pull reset outputs, one is referenced to VCC1 and the other is referenced to VCC2. The MAX6353/MAX6356/MAX6359 offer an active-low, push-pull reset output referenced t...
