The BQ24123RHLR from Texas Instruments is a highly integrated, switched-mode charge management IC for Li-ion and Li-polymer battery packs. This device is suitable for a wide range of portable applications, offering enhanced EMI performance.
Key electrical specifications include an input voltage range of 4.35 V to 16 V, with an absolute maximum rating of 20 V. It supports battery charge voltages from 2.1 V to 15.5 V and can deliver a maximum charge current of 2A. The charger operates as a synchronous fixed-frequency PWM controller at 1.1 MHz. It is designed for 1, 2, or 3-cell battery configurations.
Features include BAT temperature thermistor monitoring for hot/cold profiles, input overvoltage protection (OVP), and accurate high-side battery current sensing. The device also incorporates automatic sleep mode for low power consumption, reverse leakage protection, and thermal shutdown. Status outputs are provided for charge-in-progress, charge completion, and fault conditions, suitable for LED indication or host processor interface.
The BQ24123RHLR is available in a 20-pin VQFN package measuring 3.5 mm x 4.5 mm. The mounting type is surface mount, making it suitable for compact designs.
