MCP111/112

Micropower Voltage Detector

Features

Description

• Ultra-low supply current: 1.75 µA (max.)

• Precision monitoring options of:

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.

- 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 V_OUTpin:

- MCP111 active-low, open-drain

- MCP112 active-low, push-pull

• Available in SOT23-3, TO-92 and SC70 packages

• Temperature Range:

The MCP111 has an open-drain output with an active-

low pin (V_OUT). This device will assert V_OUTwhen the

voltage on the V_DDpin is below the trip-point voltage.

- Extended: –40°C to +125°C

(except MCP1XX-195)

The MCP112 has a push-pull output and will assert an

active-low signal (V_OUTpin) when the voltage on the

V_DDpin is below the trip-point voltage.

- Industrial: –40°C to +85°C (MCP1XX-195 only)

During operation, the output (V_OUT) remains at a logic-

high as long as V_DDis greater than the specified

threshold voltage. When V_DDfalls below the voltage

trip point, V_OUTis driven low.
