Introduction
1.1
bq2416x IC Features
The bq24160/161/163/168 integrates a synchronous PWM controller, power MOSFETs, input-current
sensing, high-accuracy current and voltage regulation, charge termination and power path management
into a QFN package. The charge parameters can be programmed through an I
circuit (IC) features include:
•
High-efficiency, fully integrated, NMOS-NMOS, synchronous buck charger with 1.5-MHz frequency
•
Integrated power FETs for up to 2.5-A charge rate
•
Power path management between battery and system voltages
For details, see the bq24160/161/163/168 data sheet (SLUSAO0).
