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 is generated, which forces reset to the active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the active state for approximately 350ms to allow the power supply and processor to stabilize.

Key Features

Automatically restarts microprocessor after power failure Maintains reset for 350ms 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 sensor Low-cost TO-92 package or surface mount SOT-223 package Internal 5k pullup resistor Compatible with Motorola 68XXX series and HC16 Microprocessors Operating temperature of -40°C to +85°C
