19-1568; Rev 2; 12/05 6-Pin µP Reset Circuit with Power-Fail Comparator MAX6342­MAX6345 General Description Features The MAX6342­MAX6345 family of microprocessor (µP) Small 6-Pin SOT23 Package supervisory circuits monitors power supplies in digital sys-tems. These devices significantly improve system reliabili- Precision Factory-Set VCC Reset Thresholds ty and accuracy compared to separate ICs or discrete Between 2.33V and 4.63V components. Guaranteed RESET Valid to VCC = +1V The MAX6342­MAX6345 provide factory-trimmed VCC 100ms min Reset Pulse Width reset threshold voltages from 2.33V to 4.63V and operatewith supply voltages between +1V and +5.5V. A +1.25V Debounced CMOS-Compatible Manual-Reset threshold detector allows for a power-fail warning, for Input low-battery detection, or for monitoring another powersupply. The MAX6342 contains an MR input and an Voltage Monitor for Power-Fail or Low-Battery active-low push-pull reset. The MAX6343 and MAX6344 Warning are identical to the MAX6342 except they provide an Ordering Information active-low, open-drain reset and an active-high, push-pull reset, respectively. The MAX6345 provides a second PART TEMP RANGE PIN-PACKAGE reset output in place of the MR input to give it an active- MAX6342_UT-T -40°C to +125°C 6 SOT23-6 high push-pull reset and an active-low push-pull reset. MAX6343_UT-T -40°C to +125°C 6 SOT23-6 All of the devices are packaged in a miniature 6-pin MAX6344_UT-T -40°C to +125°C 6 SOT23-6 SOT23. MAX6345_UT-T -40°C to +125°C 6 SOT23-6 Applications Note: The MAX6342­MAX6345 are available with factory-setreset thresholds from 2.33V to 4.63V (see Selector Guides 1, 2). Portable Computers Insert the letter corresponding to the desired nominal reset Telecom Equipment threshold into the blank following the part number. There is a2500 piece order increment required for the SOT package. SOT Networking Equipment Top Marks table appears at end of data sheet. Portable/Battery-Powered Equipment
