BQ24108RHLR Description

Short technical summary and product information.

The BQ24108RHLR from Texas Instruments is a highly efficient, standalone synchronous buck battery charger IC designed for single-cell Lithium Ion and Li-Polymer battery packs. It integrates power FETs for charge rates up to 2A and operates at a fixed 1.1 MHz frequency.

 

Key electrical specifications include a maximum charge current of 2A, a battery charge voltage of 4.2V, and an input voltage range up to 16V, with an absolute maximum rating of 20V. The device offers programmable features for current and timer control, along with fault protection for over temperature and over voltage conditions. It also includes BAT temperature thermistor monitoring for hot/cold profile charging.

 

Packaged in a 20-VQFN (3.5x4.5mm) with a surface mount type, the BQ24108RHLR operates within a temperature range of -40°C to 85°C. Its standalone control interface is RC-Settable, and it provides status outputs for charge progress, completion, and faults. This IC is ideal for applications requiring efficient charger designs in portable media players, handheld products, and industrial equipment.
