Device Overview

Summary

The MCP100 is a voltage supervisory device 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.

Additional Features
  • Holds microcontroller in reset until supply voltage reaches stable operating level
  • Resets microcontroller during power loss
  • Precision monitoring of 3V, 3.3V and 5V systems
  • 7 voltage trip points available
  • Active low RESET pin (MCP100) or active high RESET (MCP101)
  • Push-pull output
  • Holds RESET for 350ms (typical)
  • RESET to VDD = 1.0V
  • Accuracy of +(-)125mV for 5V systems and +(-)75mV for 3V systems over temp
  • 45uA typical operating current
  • Temperature range:-Industrial (I): -40C to +85C

Voltage Supervisor Evaluation Board
Voltage Supervisor Evaluation Board ( VSUPEV )

The Voltage Supervisor SOT23 Evaluation Board allows the system designer to quickly evaluate the operation of Microchip’s Voltage Supervisors and Voltage Detectors in the SOT-23-3 package. The board has been made generic so that other SOT-23-3 devices (such as LDOs and Voltage References) may also be evaluated using this board. This kit comes with four blank PCBs to allow the designer to...
