DS1817 Active High 3.3V EconoReset

TO-92 1 RST 2 VCC 3 GND Active High Reset Output Power Supply Ground SOT-23 1 RST 2 VCC 3 GND Active High Reset Output Power Supply Ground DESCRIPTION The DS1817 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 .

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 § Accurate 5%, 10% or 20% power monitoring § 20% tolerance for use with 3.0-volt systems § Low-cost TO-92 or space saving surface mount SOT-23 packages available § Push-pull active high output § Operating temperature -40°C to +85°C PIN ASSIGNMENT DALLAS DS1817 Econo Reset 3 123 123 BOTTOM VIEW TO-92 PACKAGE See Mech.
