MAX809 - 3-Pin Microprocessor Reset Circuits

Download the MAX809 datasheet PDF. This datasheet also covers the MAX803 variant, as both devices belong to the same 3-pin microprocessor reset circuits family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX803/MAX809/MAX810 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems.

They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits.

Key Features

  • Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages.
  • Fully Specified Over Temperature.
  • Available in Three Output Configurations.
  • Open-Drain RESET Output (MAX803).
  • Push-Pull RESET Output (MAX809).
  • Push-Pull RESET Output (MAX810).
  • 140ms (min) Power-On-Reset Pulse Width.
  • 12μA Supply Current.
  • Guaranteed Reset Valid to VCC = +1V.
  • Power Supply Transient Immunity.
  • No External.

MAX803/MAX809/ MAX810 3-Pin Microprocessor Reset Circuits General Description The MAX803/MAX809/MAX810 are microprocessor (μP) supervisory circuits used to monitor the power supplies in μP and digital systems. They provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3.0V, or +2.5V powered circuits. These circuits perform a single function: they assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The MAX803 has an open-drain output stage, while the MAX809/MAX810 have push-pull outputs.
