PMIC - Battery Chargers - BQ24250RGET application field and working principle

The BQ24250RGET is a 2-cell direct charge switching current/voltage battery charger from Texas Instruments Incorporated. It is a smart and versatile charger for Li-ion/Li-Pol rechargeable batteries from 2.5V to 4.5V with a maximum charging current of 2.5A or 3.0A with high-speed switching and constant voltage/current outputs. The BQ24250RGET features a wide-range input voltage from 4.5V to 20V, enabling fast charging for USB-C PD, USB-PD enabled power banks/chargers, and USB wall/computer adaptors. It also supports onboard fuel Gauging, making it ideal for embedded applications with low-power modules. The BQ24250RGET is optimized for USB-C PD and USB-PD enabled customer applications with integrated data communication, allowing the device to switch between different power profiles, automatically respond to requests for power via generated messages, and complete authentication. The device also provides inline monitoring of charge output, power connection/disconnection detection, and temperature sensing of the battery pack.The BQ24250RGET\'s high-speed switching charge pump allows for a smooth changeover from voltage to current by automatically reducing or increasing the input voltage to deliver the optimal charge to the battery. This charge pump is protected against overvoltage, short circuits, and over temperature with a Current Sense system for accurate measuring of the load current. The integrated over-voltage protection and brown-out detection ensure that the charging process is safe, reliable, and consistent. The BQ24250RGET is an ideal choice for mobile product designers who need the most reliable and efficient charging solution for their mobile products. It provides the most flexibility with its wide range of input voltage, wide compatibility with various battery chemistries, and high-speed switching charge pumps that can deliver the fastest charge times possible. Furthermore, its feature-rich solutions make it the ideal choice for today’s mobile electronic designs.
