BQ24123RHLT Description

Short technical summary and product information.

The BQ24123RHLT from Texas Instruments is a highly integrated, single-chip switched-mode charge management IC for Li-ion and Li-polymer battery packs. This device is suitable for portable applications and supports 1, 2, or 3 cell configurations.

 

Key electrical specifications include a maximum charge current of 2A, an input voltage range from 4.35V to 16V, and a battery charge voltage range of 2.1V to 15.5V. The charger operates at a fixed frequency of 1.1 MHz with a synchronous buck topology. It features programmable current and timer functions, along with fault protection for over-temperature conditions.

 

The device is housed in a 20-VQFN (3.5x4.5 mm) package, designed for surface mounting. The operating temperature range is -40°C to 85°C. Enhanced EMI performance and integrated power FETs are notable design features, making it suitable for applications requiring efficient battery charging with reduced electromagnetic interference.
