The Texas Instruments BQ24705RGERG4 is a high-efficiency, synchronous battery charger designed for multi-chemistry battery charging applications. It features integrated compensation and a low component count, making it suitable for space-constrained designs.
Key electrical specifications include an 8A charge current, an output voltage range of 8V to 18V, and a supply voltage range of 5V to 24V. The device operates at a switching frequency of 600 kHz and offers high accuracy in voltage and current regulation, with charge voltage accuracy of ±0.5% and charge current accuracy of ±3%. It also includes features like ±3% adapter current accuracy and ±2% input current sense amp accuracy.
Designed for robust operation, the BQ24705RGERG4 has a wide operating temperature range of -40°C to 125°C (TJ). It incorporates safety features such as input overvoltage protection (OVP) and dynamic power management (DPM). The charger boasts over 95% efficiency and a maximum effective duty cycle of 99.5%, with a minimum driver dead-time of 30ns.
This component is housed in a 24-VQFN (4x4) package, suitable for surface mounting. Its RoHS status is compliant, and it is classified under MSL 1 Unlimited.
