Features, Applications

The MAX6342MAX6345 family of microprocessor (P) supervisory circuits monitors power supplies in digital systems. These devices significantly improve system reliability and accuracy compared to separate ICs or discrete components. The MAX6342MAX6345 provide factory-trimmed VCC reset threshold voltages from to 4.63V and operate with supply voltages between +1V and A +1.25V threshold detector allows for a power-fail warning, for low-battery detection, or for monitoring another power supply. The MAX6342 contains an MR input and an active-low push-pull reset. The MAX6343 and MAX6344 are identical to the MAX6342 except they provide an active-low, open-drain reset and an active-high, pushpull reset, respectively. The MAX6345 provides a second reset output in place of the MR input to give it an activehigh push-pull reset and an active-low push-pull reset. All of the devices are packaged in a miniature SOT23. o Small 6-Pin SOT23 Package o Precision Factory-Set VCC Reset Thresholds Between 2.33V and 4.63V o Guaranteed RESET Valid to VCC o 100ms min Reset Pulse Width o Debounced CMOS-Compatible Manual-Reset Input o Voltage Monitor for Power-Fail or Low-Battery Warning
