MAX6414UK16-T

低功耗，单/双电压复位电路，带有电容可调的复位超时周期 Low-Power, Single/Dual-Voltage uP Reset Circuits with Capacitor-Adjustable Reset Timeout Delay

General Description

The MAX6412–MAX6420 low-power microprocessor supervisor circuits monitor system voltages from 1.6V to 5V. These devices are designed to assert a reset signal whenever the VCCsupply voltage or RESET IN falls below its reset threshold or the manual reset input is asserted.

The reset output remains asserted for the reset timeout period after VCC and RESET IN rise above the reset threshold and the manual reset input is deasserted. The reset timeout is externally set by a capacitor to provide more flexibility.
