DS1833 5V EconoReset

PIN 1 Ground PIN 2 Reset PIN 3 PIN 4 VCC Ground (SOT-223 only) DESCRIPTION The DS1833 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 .

DS1833 Features

* Automatically restarts microprocessor after power failure

* Maintains active-high 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-c
