The BQ24195RGET from Texas Instruments is an I2C controlled single cell battery charger IC designed for lithium-ion/polymer batteries. It supports a charge current of up to 4.5A and offers a synchronous boost converter with a 5.1V output at 2.1A.
This charger operates within an input voltage range of 3.9V to 17V and features high charge efficiency up to 92% at 2A and 90% at 4A. The boost converter achieves up to 94% efficiency at 1A and 91% at 2.1A. It includes fault protection for over current, over temperature, and over voltage conditions.
The device is housed in a 24-VQFN (4x4) package and is designed for surface mount applications. It operates across a temperature range of -40°C to 85°C. The charger utilizes a 1.5MHz switching frequency for a low-profile inductor solution and offers precise charge voltage and current regulation.
Key electrical specifications include ±0.5% charge voltage regulation and ±7% charge current regulation. It also features a low battery discharge MOSFET resistance of 12mΩ, enabling up to 9A discharge current.
