MCP120T-270I/TT Description

Short technical summary and product information.

The Microchip Technology MCP120T-270I/TT is a voltage supervisory device that ensures a microcontroller operates within a stable supply voltage range. It holds the microcontroller in reset until the supply voltage reaches a proper, stabilized level and also protects against brown-out conditions when the voltage drops below a safe operating threshold.

 

This device features a single voltage monitoring channel with a trip point of 2.75V. The RESET output is active low and configured as open drain or open collector. It operates with a supply voltage ranging from 1.0V to 5.5V and consumes a typical operating current of 45 µA. The device is specified for an industrial temperature range of -40°C to +85°C.

 

The MCP120T-270I/TT is supplied in a compact SOT-23-3 surface-mount package, making it suitable for space-constrained applications. Its primary function is to provide reliable power-on reset and brown-out detection for embedded systems.
