Device Overview

Summary

The MCP101 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). MCP101 is available in a TO-92 or SOT23-3 packages.

(Not Recommended for new design)

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...
