Power management integrated circuit, or PMIC, is an important part of any electronic design. It integrates a variety of power-related functions and helps make the electronic design simpler, more reliable, and less expensive. A particular type of PMIC, called a battery charger, is used to manage the charging of a battery or other energy storage device. The LM3622MX-8.2 is one such example of a PMIC battery charger.

The LM3622MX-8.2 is a PMIC battery charger specifically designed for charging one-cell lithium-ion and lithium-polymer batteries. It has a wide range of applications in both consumer and industrial products including laptops, mobile phones, tablets, digital cameras, and other hand-held devices. It is suitable for both fast and slow charging. The chip also includes integrated safety features that protect against over-voltage, over-temperature, overcharging, and short-circuit conditions.

The LM3622MX-8.2 features a highly efficient inductive step-down converter that provides a regulated output voltage adjustable up to 8.2V. It supports both Constant Voltage (CV) and Constant Current (CC) charging modes. In CV mode, the battery is charged at a constant voltage up to 4.2V, while in CC mode the battery is charged to 4.2V with a constant current. In either mode, the chip will automatically switch to a low-power standby mode once the charging is complete.

The LM3622MX-8.2 also includes an integrated pre-charge and boost converter that can be used to kick-start the charging process when the battery is depleted. It has a low-current Active Discharge function to reduce the battery voltage in order to safely disconnect the battery from the charger. It also includes a programmable timer feature that allows the user to set the desired charging time and receive alerts when the timer expires.

The LM3622MX-8.2 also includes an integrated USB power-path multiplexer that allows power to be supplied to the battery directly, or to pass it through the USB connector. This can be used to facilitate fast charging through the USB port, or to use the USB port as a charging input source. Finally, the chip includes an integrated temperature sensor and a status indicator LED.

Overall, the LM3622MX-8.2 is a PMIC battery charger that provides a solution for safe and efficient charging of lithium-ion and lithium-polymer batteries. It includes an integrated step-down converter, pre-charge converter, boost converter, USB power-path multiplexer, timer, temperature sensor, and an LED status indicator. The chip provides a high level of flexibility and can be used in a wide variety of electronic designs.
