1 / 22 page  2004 Microchip Technology Inc. DS21889B-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 and SC70 packages • Temperature Range: - Extended: –40°C to +125°C (except MCP1XX-195) - Industrial: –40°C to +85°C (MCP1XX-195 only) Applications • Critical µC and µP Power-monitoring Applications • Computers • Intelligent Instruments • Portable Battery-Powered Equipment Block Diagram Description The MCP111/112 are voltage-detecting devices designed to keep a microcontroller in reset until the system voltage has reached, and 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 a safe operating level. The MCP111 and MCP112 are available in eight different trip voltages. The MCP111 has an open-drain output with an active- low pin (VOUT). This device will assert VOUT when the voltage on the VDD pin is below the trip-point voltage. The MCP112 has a push-pull output and will assert an active-low signal (VOUT pin) when the voltage on the VDD pin is below the trip-point voltage. During operation, the output (VOUT) remains at a logic- high as long as VDD is greater than the specified threshold voltage. When VDD falls below the voltage trip point, VOUT is driven low.
