BQ25792RQMR Battery charger IC Lithium Ion/Polymer Detailed Overview
The BQ25792RQMR is a high-efficiency, multi-chemistry battery charge controller from Texas Instruments, designed for single-cell to 4-series cell battery applications. This advanced power management IC features 3.5V to 24V input voltage range with 1-4 cell battery support, delivering up to 6A charge current with 96% peak efficiency. Packaged in a 40-pin 4mm × 4mm VQFN (RQM), it integrates USB Power Delivery (PD) 3.0 support, making it ideal for modern portable devices requiring fast charging capabilities.
USB PD charger Key Features
The BQ25792RQMR stands out with its buck-boost topology that maintains optimal charging across varying input voltages. It incorporates I²C programmable charging parameters, input current optimization (ICO), and battery authentication support. The device offers comprehensive protection features including over-voltage, over-current, and thermal shutdown. Its dynamic power management automatically adjusts input power allocation between system and battery charging. The 20mV charge voltage regulation accuracy ensures precise battery care, while 1% charge current accuracy maintains consistent performance.
Battery charger IC Applications
This charger IC is perfect for high-end laptops, tablets, power banks, and USB PD-compatible devices. It's particularly valuable in medical portable equipment, industrial handheld terminals, and professional audio/video gear where reliable power delivery is critical. The solution also serves well in smart home devices, drones, and robotics applications requiring flexible power management with battery protection.
Buck-boost charger Selection Advantages
The BQ25792RQMR provides industry-leading integration, combining charger, power path management, and USB PD control in a single chip. Its adaptive input current limiting prevents source overload while maximizing charge speed. Compared to discrete solutions, it offers smaller footprint, better thermal performance, and reduced development time. The wide operating temperature range (-40°C to +85°C) ensures reliability in demanding environments.
