Function : Low-Voltage uP Supervisor with Manual Reset and Watchdog Timer

Package : SOT23-5 Type

Maker : Maxim Integrated

Pinouts :
MAX6821 datasheet

Description :

The MAX6821, MAX6825 are low-voltage microprocessor (µP) supervisory circuits that combine voltage monitor ing, watchdog timer, and manual reset input functions in a 5-pin SOT23 package. Microprocessor supervisory circuits significantly improve system reliability and accuracy compared to separate ICs or discrete components.


These devices assert a reset signal whenever the monitored voltage drops below its preset threshold, keeping it asserted for a minimum timeout period after VCCrises above the threshold. In addition, a watchdog timer monitors against code execution errors. A debounced manual reset is also available. The MAX6821–MAX6825 monitor voltages from +1.8V to +5.0V. These outputs are guaranteed to be in the correct state for VCCdown to +1.0V.

Applications : 

1. Set-Top Boxes

2. Computers and Controllers

3. Embedded Controllers

4. Intelligent Instruments

5. Critical μP Monitoring

6. Portable/Battery-Powered Equipment
