Microchip MCP130T Voltage Supervisor 3.15V Threshold SOT-23-3

The Microchip MCP130T Voltage Supervisor provides a 3.15V reset threshold to help protect microcontrollers and digital systems. It monitors the supply voltage (VDD) and holds a microcontroller in a reset state until the power rail has stabilised at a safe operating level.

Overview

The supervisor helps guard against brown-out conditions, where a dip in supply voltage could cause erratic behaviour or data corruption. It asserts a reset signal whenever VDD falls below its preset threshold, supporting controlled startup and shutdown of sensitive electronics and helping to prevent code execution errors during unstable power conditions.

Key Features

• Active-low, open-drain reset output for integration into a range of logic systems
• Fixed 350ms reset delay after the supply voltage rises above the threshold
• Threshold accuracy of ±75mV for 3V systems over a wide temperature range
• Supply voltage range of 1V to 5.5V
• Typical operating current of 45µA
• Integrated 5kΩ internal pull-up resistor on the reset output

Specifications

• Package: SOT-23-3 surface-mount
• Operating temperature range: -40°C to 85°C
• Qualified to AEC-Q100 for automotive applications

The device suits power-conscious designs and applications that require dependable reset control. Its compact SOT-23-3 surface-mount package is designed for automated assembly, making it a practical choice for adding power-on reset supervision to digital circuits.
