Power management integrated circuits commonly known as PMICs are one of the most integral parts of any electronic device. PMICs enable the efficient functioning of each electronic component in a device, allowing the device to work at maximum efficiency while conserving energy. The MCP73853-I/ML is one such PMIC, it is a highly efficient battery charger designed to be used with single cell Li-Ion or Li-Po batteries. This PMIC allows the battery to be recharged safely and quickly while under constant monitoring, protecting it from any potential damage by overcharging or over-discharging. This article explores the application fields and working principles of the MCP73853-I/ML.

Application Field

The MCP73853-I/ML is an ideal battery charger for handheld and portable electronics such as calculators, phones, digital cameras, and other portable electronics. It is a highly efficient PMIC which can charge up to two cells in series and has an output current of up to 250mA. The integrated current control circuit is designed to provide a constant current or adjustable current source for charging. Furthermore, the MCP73853-I/ML can be configured for stand-alone charge and discharge control as well as for temperature accuracy and over-voltage protection.

It is also suitable for use in automotive applications, providing charging solutions for start-stop vehicles, electric vehicles, personal electronic devices, and communication and industrial applications. Its cost-efficiency, small size, and low power consumption make it an ideal candidate for automotive applications.

Working Principles
