MAX6357：双/三电压微处理器监控电路

业内首款多电压监控电路，采用SOT封装

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 to VCC1. The MAX6354/MAX6357/MAX6360 offer an active-low, push-pull reset output referenced to VCC2. All these devices are offered with a wide variety of voltage threshold levels, as shown in the Voltage Threshold Levels table. They are available in 5- and 6-pin SOT23 packages and operate over the extended (-40°C to +85°C) temperature range.
