Product Overview

The DS1813-5+T&R is a 5V EconoReset with pushbutton in 3 pin TO-92 package. This EconoReset function is to detect out of tolerance power supply conditions and warning processor-based system of impending power failure. It uses a precision temperature reference and comparator circuit to monitor 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 active state. When VCC returns to an in-tolerance condition, reset signal is kept in active state for approximately 150ms to allow power supply and processor to stabilize. It provides a pushbutton switch for manual reset control which monitors a pushbutton on the reset output. If the reset line is pulled low a reset is generated upon release and will be held in reset output low for typically 150ms.
  • Supply voltage range is 0V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Automatically restarts a microprocessor after power failure
  • Monitors pushbutton for external override
  • Reduces need for discrete components
  • Efficient open-drain output with internal 5.5Kohm pull-up resistor
  • Typical VCC trip point is 4.62V
  • Output capacitance of 10pF at VCC = 1.2V to 5.5V (TA = -40°C to +85°C)
  • Precision temperature-compensated voltage reference and voltage sensor
