TEXAS INSTRUMENTS BQ24172EVM-706-15V 评估模块, BQ24172EVM-706-15V
The is an Evaluation Module for evaluate the operation and performance of BQ24172, a 1.6MHz synchronous switch-mode Li-Ion and Li-Polymer battery charger. The board is also called the HPA706 -002. This board is optimized for a 12 or 15V input voltage and charges between 1 and 3 cell Li-Ion batteries. 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.
