DS1233D, 5V EconoReset

PIN 1 PIN 2 PIN 3 PIN 4 GROUND RESET VCC GROUND (SOT-223 ONLY) DESCRIPTION The DS1233D EconoReset uses a precision temperature-compensated 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

DS1233D Features

* Automatically restarts microprocessor after power failure Maintains reset for 350 ms after VCC returns to an in-tolerance condition Accurate 5%, 10% or 15% microprocessor 5V power supply monitoring Reduces need for discrete components Precision temperature-compensated voltage reference and voltage s
