MAX6340 - Low-Power / SC70/SOT uP Reset Circuits

General Description

The MAX6340/MAX6421

MAX6426 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V.

These devices perform a single function: they assert a reset signal whenever the VCC supply voltage falls below its reset threshold.

Key Features

  • Monitor System Voltages from 1.6V to 5V.
  • Capacitor-Adjustable Reset Timeout Period.
  • Low Quiescent Current (1.6µA typ).
  • Three RESET Output Options Push-Pull RESET Push-Pull RESET Open-Drain RESET.
  • Guaranteed Reset Valid to VCC = 1V.
  • Immune to Short VCC Transients.
  • Small 4-Pin SC70, 4-Pin SOT143, and 5-Pin SOT23 Packages.
  • MAX6340 Pin Compatible with LP3470.
  • MAX6424/MAX6425 Pin Compatible with NCP300.

MAX6340/MAX6421– MAX6426 Low-Power, SC70/SOT µP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay General Description The MAX6340/MAX6421–MAX6426 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices perform a single function: they assert a reset signal whenever the VCC supply voltage falls below its reset threshold. The reset output remains asserted for the reset timeout period after VCC rises above the reset threshold. The reset timeout is externally set by a capacitor to provide more flexibility. The MAX6421/MAX6424 have an active-low, pushpull reset output.
