MCP73833T-B6I/MF

PMIC, or Power Management Integrated Circuit, is an electronic system which provides and manages power on a circuit set, often made for specific uses and models of electronic equipment. Battery chargers are a type of PMIC, and the MCP73833T-B6I/MF is a type of linear Li-Ion/Li-Polymer battery charger, which is a more precise form of charging and discharging lithium-ion batteries than typical PMICs. The MCP73833T-B6I/MF provides the user with a convenient way to charge and protect their battery with only one integrated circuit.

The MCP73833T-B6I/MF was designed to provide an economical, small size solution to charge single-cell Li-Ion/Li-Polymer batteries. The integrated circuit combines all of the necessary components and functions to charge Li-Ion/Li-Polymer cells, from voltage based battery expert selection and fast-charge control, to the actual circuitry for pre-charge and charging. The integrated fast charge control reduces the total charge time for a battery, and by including all the necessary circuits, the MCP73833T-B6I/MF reduces its overall size, making it more space efficient.

The IC contains a microcontroller, allowing the user to customize their charging parameters and edit features such as maximum fast charge time, precharge time and differential voltage. The IC also includes an 8-bit digital signal processor to guarantee accuracy, such as make sure the battery will be protected from over-charging. Protection mechanisms such as short circuit protection, thermal sense shutdown, reverse charge protection and charge overvoltage protection are also included to ensure safety and reliability during the charging process.

The MCP73833T-B6I/MF’s working principle is based on the fact that when a battery is connected, the IC will draw a small current since the battery is not at its full charge. This current will then cause the control IC to start the pre-charge process, by feeding the sense input of the IC to the external system, allowing the IC to adjust the current and voltage accordingly. The pre-charge process is the first stage of the charging procedure, and it ensures that the battery will not be supplied with a voltage or current which is too high. Once the battery has reached its pre-charge voltage, the charging algorithm will start.

The charging algorithm is then activated, as it begins to apply a constant-current or constant-voltage charging regime to the battery. This charging regime will depend on the voltage and current sensing. The battery charges according to the voltage and current felt within it, and the MCP73833T-B6I/MF will adjust the voltage and current it supplies in accordance. The charging algorithm also contains an end-of-charge detection method, which monitors the battery voltage and temperature, so that it can accurately detect when the battery is fully charged and automatically stop the charging process.

The MCP73833T-B6I/MF is primarily designed for mobile devices such as cellular phones, digital camcorders and PDAs, as well as battery-based products such as emergency lighting, model toys and GPS systems. It is also suitable for virtually any other application, as long as the parameters for the battery current, voltage, voltage tolerance and temperature tolerance are met. The IC is capable of not only charging the battery, but managing it as well, displaying data on the charging process such as battery health and the system’s total power usage. This makes the MCP73833T-B6I/MF an excellent choice for anyone looking for a reliable, cost-effective solution for powering their applications.
