BQ24170RGYR datasheet

Description :

The BQ24170RGYR, bq24170/bq24172 is highly integrated stand-alone Li-ion and Li-polymer switch-mode battery charger with two integrated N-channel power MOSFETs. It offers a constant-frequency synchronous PWM controller with high accuracy regulation of input current, charge current, and voltage. It closely monitors the battery pack temperature to allow charge only in a preset temperature window. It also provides battery detection, pre-conditioning, charge termination, and charge status monitoring. The thermal regulation loop reduces charge current to maintain the junction temperature of 120°C during operation.

The bq24170/bq24172 charges the battery in three phases: precondictioning, constant current, and constant voltage. The bq24170 charges one, two, or three cells (selected by CELL pin), and the bq24172 is adjustable for up to three series Li+ cells.
