MXD1811 Datasheet Low-power Up Reset Circuits

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MXD1810–MXD1813/ MXD1815–MXD1818 Low-Power μP Reset Circuits in 3-Pin SC70/SOT23.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MXD1810–MXD1813/MXD1815–MXD1818 family of microprocessor (μP) reset circuits monitor power supplies in μP and digital systems.

These devices provide excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V/+3.0V/+3.3V (MXD1815–MXD1818), and +5V (MXD1810–MXD1813) systems.

These circuits assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping reset asserted for at least 100ms after VCC rises above the reset threshold.

Key Features

  • Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages.
  • Available in Four Reset Output Configurations.
  • Factory-Set Reset Threshold Voltages: 2.18V, 2.31V, 2.55V, 2.88V, 3.06V, 4.12V, 4.37V, 4.62V.
  • ±2.5% Reset Threshold Accuracy Over Temperature.
  • Fixed Reset Timeout Period: 100ms (min).
  • Guaranteed RESET/RESET Valid to VCC = +1V.
  • Debounced Manual-Reset Detect (MXD1813/ MXD1818).
  • Power-Supply Transien.
