1 / 26 page © 2005 Microchip Technology Inc. DS21889D-page 1 MCP111/112 Features • Ultra-low supply current: 1.75 µA (max.) • Precision monitoring options of: - 1.90V, 2.32V, 2.63V, 2.90V, 2.93V, 3.08V, 4.38V and 4.63V • Resets microcontroller in a power-loss event •Active-low VOUT pin: - MCP111 active-low, open-drain - MCP112 active-low, push-pull • Available in SOT23-3, TO-92, SC-70 and SOT-89-3 packages • Temperature Range: - Extended: -40°C to +125°C (except MCP1XX-195) - Industrial: -40°C to +85°C (MCP1XX-195 only) • Pb-free devices Applications • Critical Microcontroller and Microprocessor Power-Monitoring Applications • Computers • Intelligent Instruments • Portable Battery-Powered Equipment Description The MCP111/112 are voltage-detecting devices designed to keep a microcontroller in reset until the system voltage has stabilized at the appropriate level for reliable system operation. These devices also operate as protection from brown-out conditions when the system supply voltage drops below the specified threshold voltage level. Eight different trip voltages are available.
