General Description

TO-92 1 RST 2 VCC 3 GND Active Low Reset Output Power Supply Ground SOT-23 1 RST 2 VCC 3 GND Active Low Reset Output Power Supply Ground DESCRIPTION The DS1811 EconoReset uses a precision temperature 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 150 ms to allow the power supply and processor to stabilize.

Overview

www.maxim-ic.com DS1811 5V EconoReset with Open Drain Output.

Key Features

  • Automatically restarts a microprocessor after power failure.
  • Maintains reset for 150 ms after VCC returns to an in-tolerance condition.
  • Reduces need for discrete components.
  • Precision temperature-compensated voltage reference and voltage sensor.
  • Low-cost TO-92 or space saving SOT-23 packages available.
  • Efficient open-drain output with internal 5.5 kW pull-up resistor.
  • Operating temperature -40°C to +85°C PIN.
