产品概述

The DS1834S+ is a dual EconoReset with pushbutton in 8 pin NSOIC package. This EconoReset monitors three vital system conditions such as 5V supply, 3.3V supply and an external override. First a precision temperature reference and comparator circuit monitor the status of 5V supply and 3.3Vsupply. When an out of tolerance condition is detected an internal power-fail signal is generated which forces reset of the affected supply to an active state. It provides a pushbutton switch for manual reset control which supports an external reset via an internally debounced pushbutton input. When pushbutton is pulled low both resets will be asserted for approximately 350ms after the pushbutton is released.
  • Supply voltage range is 1.2V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Internal power is drawn from higher of either the 5VIN input or the 3.3VIN input
  • Excellent for systems designed to operate with dual power supplies
  • Asserts resets during power transients
  • Reduces need for discrete components
  • Precision temperature-compensated voltage reference and voltage sensor
  • CMOS output for low current operation
