MAX6822 Datasheet Low-voltage Sot23 Up Supervisors

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1868; Rev 1; 1/01 Low-Voltage SOT23 µP Supervisors with Manual Reset and Watchdog.

General Description

The MAX6821–MAX6825 are low-voltage microprocessor (µP) supervisory circuits that bine voltage monitoring, watchdog timer, and manual reset input functions in a 5-pin SOT23 package.

Microprocessor supervisory circuits significantly improve system reliability and accuracy pared to separate ICs or discrete ponents.

These devices assert a reset signal whenever the monitored voltage drops below its preset threshold, keeping it asserted for a minimum timeout period after VCC rises above the threshold.

Key Features

  • o Monitors +1.8V, +2.5V, +3.0V, +3.3V, +5.0V Supplies o 140ms (min) Reset Timeout Delay o 1.6s Watchdog Timeout Period (MAX6821/MAX6822/MAX6823/MAX6824) o Manual Reset Input (MAX6821/MAX6822/MAX6823/MAX6825) o Three Reset Output Options Push-Pull RESET Push-Pull RESET Open-Drain RESET o Guaranteed Reset Valid to VCC = +1.0V o Immune to Short Negative VCC Transients o No External Components o Small 5-Pin SOT23 Packages MAX6821.
