DS1834A Datasheet Dual Econoreset

Manufacturer: Dallas Semiconductor

Overview: www.DataSheet4U.com DS1834/A/D Dual EconoReset with Pushbutton www.dalsemi.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

5VIN 5V RST (*RST) 5V TOL GND - 5V Power Supply Input - 5V Reset Output - Selects 5V Input Tolerance - Ground PBRST - Pushbutton Reset 3.3V TOL - Selects 3.3V Input Tolerance 3.3V RST (*RST) - 3.3V Reset Output 3.3VIN - 3.3V Power Supply Input *DS1834D Active High Reset DESCRIPTION The DS1834 Dual EconoResets monitors three vital system conditions: 5-volt supply, 3.3-volt supply, and an external override.

First a precision temperature reference and comparator circuit monitor the status of the 5-volt supply and the 3.3-volt supply.

When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces the reset of the affected supply to an active state.

Key Features

  • 5V power-on reset 3.3V power-on reset 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 Pushbutton reset input for system override Maintains reset for 350 ms after VCC returns to an in-tolerance condition Reduces need for discrete components Precision temperature-compensated voltage reference and voltage sensor 8-pin DIP, 8-pin SOIC, and 8-pin µ-SOP available C.
