Technical details

750mA linear charger for single-cell Li-Ion/Polymer packs

The TI BQ24085DRCR is a linear battery charger IC designed for single-cell lithium-ion and lithium-polymer packs, targeting a 4.2V full-charge voltage with a programmable constant-current charge up to 750mA. A programmable timer controls the charge termination — no I²C or SMBus interface needed, making it a straightforward drop-in for portable equipment where a simple hardware-timed charge cycle is sufficient.

Fault protection set — over-temp, over-voltage, short-circuit

On-chip fault protection covers over-temperature, over-voltage, and output short-circuit conditions — no external supervisory IC required for basic Li-ion safety compliance in consumer and industrial portable designs. The junction temperature rating spans 0°C to 125°C, allowing the charger IC to sit near the battery or inside a sealed enclosure without derating the charge current at moderate ambient temperatures.

VSON-10 exposed-pad package and supply rail

Maximum supply voltage is 6.5V; the input rail can be a 5V USB bus or a 5V wall adapter without a separate pre-regulator.

Base product number BQ24085 — the DRCR suffix is the VSON-10 reel variant; the same die is available in other package options for design flexibility.
