The BQ24155RGYR from Texas Instruments is a compact and efficient switch-mode charge management device designed for single-cell Li-ion and Li-polymer batteries. It is suitable for a wide range of portable applications, including mobile phones, MP3 players, and handheld devices.
This IC features high-accuracy voltage and current regulation, with charge voltage regulation accuracy of ±0.5% at 25°C and ±1% from 0°C to 125°C. The charge current regulation accuracy is ±5%, and input current regulation accuracy is also ±5% for 100 mA and 500 mA.
The BQ24155RGYR operates with a maximum input voltage of 6V (absolute maximum 20V) and supports a maximum charge current of 1.25A. It charges the battery in three phases: conditioning, constant current, and constant voltage. The charge parameters, including input current, fast-charge/termination current, and charge voltage (3.5V to 4.44V), can be programmed via an I2C compatible interface operating up to 3.4 Mbps.
Packaged in a 14-VQFN (3.5x3.5 mm) with an exposed pad, the BQ24155RGYR is designed for surface mounting. It includes robust protection features such as thermal regulation and protection, and input/output overvoltage protection. The device also offers automatic charging and a USB-friendly boot-up sequence.
