PMIC - Battery Chargers have become increasingly important and reliable components in the field of battery management systems. In this article, we will look at the MCP73213T-A6SI/MF application field and working principle to understand more about its usage and performance.

The MCP73213T-A6SI/MF IC is a highly popular battery charge controller IC from Microchip. It is a buck regulator-based IC that finds its application in single-cell Li-Ion/LiPo battery management systems. The IC features two internal FETs along with a powerful current monitor and voltage regulator among other components.

The charge controller features an on-board voltage regulator that provides an adjustable output voltage up to 4.2V. This output voltage can be programmed to provide up to 500mA output current depending upon the system requirements. This allows users to program the output voltage and current as per the system requirements.

The MCP73213T-A6SI/MF can be used in different types of battery management systems, such as those used in medical devices, portable electronics, phones, etc. It supports different types of charging algorithm such as Constant-Current/Constant-Voltage (CC/CV), Peak Detection and Programmable Voltage/Current (PV/PC). It also has Input Over Voltage Protection (OVP) and a Micro-Power Shutdown Mode to improve the system efficiency.

The MCP73213T-A6SI/MF IC is based on a synchronous buck regulator topology which allows it to achieve high efficiency levels up to 98%. It supports up to 4MHz of switching frequency and has a programmable limit of up to 3A output current. This makes it suitable for applications which require high power output levels.

The IC also features a Thermal Shutdown feature. This allows the IC to shut down the regulator when it detects an over-temperature event. This helps to protect the system from any damage due to the increase in temperature. Additionally, the IC also features an Over-Current Protection (OCP) and Under-Voltage Lockout (UVLO) features to further protect the circuit from any unexpected events.

In conclusion, the MCP73213T-A6SI/MF battery charge controller IC is an ideal solution for Li-Ion/LiPo battery management systems requiring longer battery life and better performance. It comes equipped with the necessary safety features such as thermal shutdown, over-voltage protection, over-current protection, and under-voltage lockout for better system performance and protection.
