MAX812 - 4-Pin uP Voltage Monitors

Download the MAX812 datasheet PDF. This datasheet also covers the MAX811 variant, as both devices belong to the same 4-pin up voltage monitors family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX811/MAX812 are low-power microprocessor (μP) supervisory circuits used to monitor power supplies in μP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5Vpowered or 3V-powered circuits.

Key Features

  • Integrated Voltage Monitor Increases System Robustness with Added Manual Reset.
  • Precision Monitoring of 3V, 3.3V, and 5V Power-Supply Voltages.
  • 140ms Min Power-On-Reset Pulse Width.
  • RESET Output (MAX811), RESET Output (MAX812).
  • Guaranteed Over Temperature.
  • Guaranteed RESET Valid to VCC = 1V (MAX811).
  • Power-Supply Transient Immunity.
  • Saves Board Space.
  • No External Components.
  • 4-Pin SOT143 Package.

MAX811/MAX812 General Description The MAX811/MAX812 are low-power microprocessor (μP) supervisory circuits used to monitor power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with 5Vpowered or 3V-powered circuits. The MAX811/MAX812 also provide a debounced manual reset input. These devices perform a single function: They assert a reset signal whenever the VCC supply voltage falls below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold.
