PMIC - Supervisors are one of the most powerful tools in the electronics industry. They can provide Time-To-Market, performance, reliability and scalability for electronic products. The MCP120T-270I/SN from Microchip products is a perfect example of a PMIC - Supervisors solution for managing embedded systems. The device has been specifically designed to provide a solution for monitoring and controlling power management in both low-power (e.g., solar panel) and high-power (e.g., brushless DC motors) applications.

The MCP120T-270I/SN is a voltaged-adapter-style supervisor that works in conjunction with a microcontroller (MCU) to provide under- and overvoltage protection. It is designed to monitor voltage changes as a result of an increase or decrease in load. The MCP120T-270I/SN has three important functions. It measures the input voltage (VIN) on a single pin, compares it against an internally programmed voltage level (VTH), and then signals an active low reset when the voltage drops below the threshold.

The MCP120T-270I/SN works on the principle of transformer-coupled voltage detection. It is provided with an auxiliary winding of a voltage transformer, which is coupled with the main winding, providing a low-level output voltage. The output voltage increases or decreases with respect to the differential voltage applied between the two windings. The output voltage is then compared to an internally set voltage threshold, and when the output voltage drops below the threshold, the MCP120T-270I/SN generates a reset signal.

The MCP120T-270I/SN is suitable for different application areas. It can be used for power management of electronic devices such as industrial electronic equipment, solar systems, brushless DC motors, or even battery cells. It ensures safe operation of the connected devices by monitoring the voltage level to prevent over-voltage as well as under-voltage conditions. It is also a perfect solution for controlling low-power applications.

The MCP120T-270I/SN works on a simple principle: input voltage is continuously monitored and compared with an internally set threshold. When the input voltage drops below the programmed threshold, the MCP120T-270I/SN generates a reset signal to indicate an undervoltage condition. The device is then reset and the power to the connected device is managed accordingly. This ensures the safe operation of the power supply.

The MCP120T-270I/SN is equipped with a number of features, such as an adjustable reset active timer, an adjustable duty cycle, an adjustable reset delay time, adjustable reset time-out period, and an undervoltage lockout. These features make it suitable for many different types of applications, from low-power devices to high-power systems and from industrial systems to brushless DC motors. This device is highly reliable, easy to maintain, and cost-effective.
