A supervisor, also known as an MCU supervisor, is a type of device designed to assist a microcontroller in resetting, validating system conditions, and monitoring power loss. Supervisors help avoid unpredictable system behavior due to loss of power, incorrect code programming, or electrical noise. The MCP102T-475E/TT supervisor is a simple integrated circuit (IC) designed to assist microcontrollers with controlling and monitoring the power input. In this article, we\'ll look at the application fields, working principles, and features of the MCP102T-475E/TT.

Application Fields

The MCP102T-475E/TT supervisor is generally used in portable electronic devices, such as tablets, laptops, and mobile phones. Its main purpose is to monitor power, reset the microcontroller, and ensure proper device functioning in spite of any power loss, incorrect code, or noise. It is best suited for applications in which there are multiple voltage sources, such as USB and Li-ion batteries, or any other power management systems that require monitoring and resetting of microcontrollers.

Working Principle

The Monolithic Control Techniques (MCP) MCP102T-475E/TT supervisor is a simple, cost-effective IC designed to monitor and reset microcontrollers. It features an ultra-low leakage MOSFET current source that is triggered when an output voltage drops too low. This threshold is adjustable via a trim potentiometer located on the IC, allowing the user to set the device\'s sensitivity.

When the voltage drops below the threshold, the MCP102T-475E/TT supervisor triggers a reset pulse. This pulse can be directed to an input pin of a microcontroller, thus allowing it to reset and resume normal functioning. The supervisor also features an undervoltage lockout (UVLO) that prevents the circuit from receiving too low of a voltage.

Features

The MCP102T-475E/TT supervisor is a low-cost IC that provides reliable power management solutions. It operates at a low power consumption of 2.5uW and its reset function is triggered at an adjustable voltage. The reset output is open drain, meaning it can directly drive an input pin of a microcontroller, making it easy to integrate. The IC also includes an enable-disable pin, allowing users to enable or disable the reset pulse as needed. The supervisor also features an under-voltage lockout that prevents the circuit from entering too low of a voltage.

The MCP102T-475E/TT supervisor is a great option for power management solutions. Its simple design and adjustable voltage threshold make it easy to integrate into existing systems, and its low power consumption ensures reliable operation. It is the perfect IC for any application that requires monitoring and resetting of microcontrollers in spite of power loss, incorrect code programming, or electrical noise.
