19-2440; Rev 4; 12/05 Low-Power, SC70/SOT µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay MAX6340/MAX6421­MAX6426 General Description Features The MAX6340/MAX6421­MAX6426 low-power micro- Monitor System Voltages from 1.6V to 5V processor supervisor circuits monitor system voltagesfrom 1.6V to 5V. These devices perform a single function: Capacitor-Adjustable Reset Timeout Period they assert a reset signal whenever the VCC supply volt- Low Quiescent Current (1.6µA typ) age falls below its reset threshold. The reset outputremains asserted for the reset timeout period after V Three RESET Output Options CC rises above the reset threshold. The reset timeout is exter- Push-Pull RESET nally set by a capacitor to provide more flexibility. Push-Pull RESET The MAX6421/MAX6424 have an active-low, push- Open-Drain RESET pull reset output. The MAX6422 has an active-high, Guaranteed Reset Valid to VCC = 1V push-pull reset output and the MAX6340/MAX6423/MAX6425/MAX6426 have an active-low, open-drain Immune to Short VCC Transients reset output. The MAX6421/MAX6422/MAX6423 are Small 4-Pin SC70, 4-Pin SOT143, and 5-Pin SOT23 offered in 4-pin SC70 or SOT143 packages. The Packages MAX6340/MAX6424/MAX6425/MAX6426 are availablein 5-pin SOT23-5 packages.
