The LX2201CLQ PMIC – Battery Charger is a dedicated integrated circuit designed to provide rapid battery charging and protection to cell-phone and other Lithium-ion battery packs while offering low power consumption.

The LX2201CLQ integrated circuit consists of a Li-Ion/Li-Po battery charger, four linear regulators, a high current synchronous buck converter, a low-dropout voltage regulator, and a USB-OTG transceiver. The integrated circuit includes protection against overvoltage, short-circuits, thermal runaway, and reverse polarity.

The integrated circuit provides a variety of useful features, such as a programmable input current limit, an adjustable output voltage and a cut-off voltage level. It also includes a low-dropout voltage regulator which enables a low-power solution without sacrificing performance.

The integrated circuit is designed to be used with a variety of battery chemistries, including Nickel Metal Hydride (NiMH) and Lithium-ion/Lithium-polymer (Li-Ion/Li-Po). It is also capable of charging batteries up to a maximum voltage of 4.2V with currents of up to 3A.

The integrated circuit works by means of a charge control loop to reduce power consumption while providing rapid and safe charging. The loop is designed to monitor the battery during charging and make adjustments to the current and voltage levels as needed to ensure optimal charging performance. The integrated circuit also includes an overvoltage protection mechanism to prevent the battery from being overcharged.

The integrated circuit is packaged in a convenient 8-pin lead-free package that can be easily surface-mounted on a compact printed circuit board. It also includes a wide operating temperature range mode to accommodate ambient conditions, a low-battery detection feature for optimal management of the battery voltage level, and an adjustable pre-charge current for faster and safer charging.

Overall, the LX2201CLQ PMIC – Battery Charger is an ideal solution for powering and charging portable devices, offering reliable and efficient performance with low power consumption.
