Product Highlight

  • No of Outputs: Single
  • Threshold Voltage: 4.5 V
  • Supply Voltage-Max: 5.5 V
  • Reset Timeout: 150 ms

The MCP100 series of voltage supervisory device is designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level.

MCP100 has a CMOS Push-Pull output with Active Low reset and is available in a choice of seven different trip voltages. It operates over the extended industrial temperature range (-40° C/+85° C). MCP100 is available in a TO-92 or SOT23-3 packages.


  • Holds microcontroller in reset untill supply vlotage reaches stable operating level
  • Resets microcontroller during power loss
  • Precision monitoring of 3 V, 3.3 V and 5 V systems
  • 7 voltage trip point available
  • Active low RESET(bar)/[MCP100] or active high RESET(MCP101)
  • Push-pull output
  • Holds RESET(bar)/[MCP100] for 350 ms (typical)
  • RESET(bar)/[MCP100] to Vdd = 1.0 V
  • Accuracy of ±125 mV for 5 V systems and ±75 mV for 3 V systems over temperature
  • 45 µA typical operating current
  • Temperature range:
    • Industrial (I): -40º C to +85º C
