BQ24030RHLR

The BQ24030RHLR from Texas Instruments is a compact, single-chip solution for managing battery charging and system power in portable devices. This IC supports dual input sources, allowing simultaneous system power and battery charging from either an AC adapter or a USB port.

Key electrical specifications include a 1-cell Li-ion/Li-Polymer battery chemistry support, a maximum charge current of 1.5A, and a battery charge voltage of 4.2V. The device operates within an input voltage range of 4.35V to 16V, with an absolute maximum input voltage of 18V. It features integrated USB charge control with selectable 100mA and 500mA input current limits and supports dynamic total current management up to 2A.

Designed for ease of integration, the BQ24030RHLR comes in a small 3.5mm x 4.5mm 20-VQFN package with an exposed pad for improved thermal performance. It offers features such as BAT temperature thermistor monitoring, an integrated 3.3V LDO output, and charge status outputs for LED indication. Fault protection includes over-temperature, reverse current, and short-circuit protection.

This IC is suitable for a wide range of portable applications including smartphones, MP3 players, digital cameras, and handheld devices, where efficient and reliable battery management is crucial.
