DS1233A Product details

Description

PIN 1 PIN 2 PIN 3 PIN 4 GROUND RESET VCC GROUND (SOT-223 ONLY) DESCRIPTION The DS1233A EconoReset monitors two vital conditions for a microprocessor: power supply and external override.A precision temperature-compensated reference and comparator circuit are used to monitor the status of the power supply (VCC).When an out-of-tolerance condition is detected, an internal power fail signal is generated which forces reset to the active state.When VCC returns to an in-tolerance condition, the res

Features

Automatically restarts microprocessor after power failure Monitors pushbutton for external override Internal circuitry debounces pushbutton switch Maintains reset for 350ms after VCC returns to an in-tolerance condition or pushbutton released Accurate 10% or 15% microprocessor 3.3V power supply monitoring Reduces need for discrete components Precision temperature-compensated voltage reference and voltage sensor Low-cost TO-92 package or.
