Texas Instruments  BQ24172EVM-706-5V

The Texas Instruments BQ24172EVM-706-5V (-001) evaluation module helps designers evaluate the operation and performance of the bq24172 synchronous battery charger. The EVM is also called the HPA706 (-001). This EVM is optimized for 5V input voltage and charges a single cell 4.2V Li-ion battery. The manual includes the BQ24172EVM-706-5V bill of materials, board layout, and schematic. The bq24172 is a highly integrated stand-alone Li-ion and Li-polymer switch-mode, battery-charge controller 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, preconditioning, charge termination, and charge status monitoring. This user's guide describes the features and operation of the BQ24172EVM-706-5V
