Product Overview

The DS1818R-5+T&R is a 3.3V EconoReset with pushbutton switch in 3 pin SOT-23 package. It uses a precision temperature compensated reference and comparator circuit to monitor the status of the power supply (VCC). When an out of tolerance condition is detected, an internal power fail signal is generated which forces reset to the active state. When VCC returns to an in tolerance condition, the reset signal is kept in the active state for approximately 150ms to allow power supply and processor to stabilize. The DS1818 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is generated upon release and the DS1818 output will be held in reset output low for typically 150ms. The DS1818 provides a pushbutton switch for manual reset control.
  • Supply voltage range from 1V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • VCC trip point of 3.06V with 5% tolerance and reset active time 150ms
  • Improves reliability of processor operation
  • Temperature compensated voltage monitor for precise, automated power fail detection
  • Automatically restarts a microprocessor after power failure
  • Monitors pushbutton for external override
  • Active-low, open-drain output with internal 5.5Kohm pull-up resistor saves power and space
  • Maximum quiescent current of 35μA
  • Allows for easy design with no complicated settings
