Product Description
Product Details
DESCRIPTION
The DS1811 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 signal is generated which forces reset to the active state. When VCCreturns to an in-tolerance condition, the reset signal is kept in the active state for approximately 150 ms to allow the power supply and processor to stabilize.
FEATURES
Automatically restarts a microprocessor after power failureMaintains 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
Low-cost TO-92 or space saving SOT-23 packages available
Efficient open-drain output with internal 5.5 kΩpull-up resistor
Operating temperature -40°C to +85°C
