BQ24901 描述

The bq24901 Li-Ion charge management devices are designed specifically for off-line charger applications. The bq24901 resides on the secondary-side of the transformer and provides the control feedback to a variety of primary side controllers. The bq24901 offers current or voltage regulation feedback, temperature monitoring, charge status, and adjustable charge termination, in a single monolithic device. During battery-absent or charge-complete conditions, the bq24901 continuously regulates the secondary-side voltage, used as VCC supply to the device. The bq24901 features a time-limited preconditioning phase to condition deeply discharged cells. The pre-conditioning phase is achieved by linear regulation in the secondary side
