LINEAR TECHNOLOGY LTC4009IUF#PBF 芯片, 电池充电器, 20QFN
The is a constant-current/constant-voltage Battery Charger Controller. It uses a synchronous quasiconstant frequency PWM control architecture that will not generate audible noise with ceramic bulk capacitors. Charge current is set by the combination of external sense, input and programming resistors. With no built-in termination, the LTC4009 family charges a wide range of batteries under external control. It features a fully adjustable output voltage. The device includes AC adapter input current limiting which maximizes the charge rate for a fixed input power level. An external sense resistor programs the input current limit and the ICL status pin indicates when the battery charge current is being reduced as a result of AC adapter current limiting. The CHRG status pin is active during all charging modes, including special indication for low charge current.
