Device Overview

Summary

The MCP1316/16M/17/18/18M/19/19M/20/21/22 are voltage supervisor devices designed to keep a microcontroller in reset until the system voltage has reached and stablized at a proper level for reliable system operation. These devices also protect from brown-out conditions when the system supply voltage drops below the specified threshold voltage level.

Additional Features
    • Low supply current
    • Precision monitoring trip point options of 2.0V to 4.7V (100 mV increment)
    • Reset microcontroller in a power loss event
    • Reset delay time-out option: (1.4 ms, 30 ms, 200 ms, 1600 ms)
    • Watchdog timer input time-out options: (6.3 ms, 102 ms, 1600 ms, 25600 ms)
    • Complementary Reset Output
    • SOT-23-5 Pb-free packaging
