Texas Instruments  BQ24170EVM-610-15V

The Texas Instruments BQ24170EVM-610-15V (-002) evaluation module helps designers evaluate the operation and performance of the bq24170 synchronous battery charger. The EVM is also called the HPA610 (-002). This EVM is optimized for a 12V or 15V input voltage and charges between 1 and 3 cell Li-Ion batteries. The bq24170 is highly integrated stand-alone Li-ion and Li-polymer switch-mode battery charge controllers with two integrated N-channel power MOSFETs and power path selector gate driver. It offers a constant-frequency synchronous PWM controller with high accuracy regulation of input current, charge current and voltage. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. This user's guide includes the EVM bill of materials, board layout, and schematic.
