LTC4012-3 High Efficiency, Multi-Chemistry Battery Charger with PowerPath Control DescripTion
The LTC®4012-3 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 external resistors and can be monitored as an output voltage across the programming resistor. With no built-in termination, the LTC4012-3 charges a wide range of batteries under external control. The LTC4012-3 features fully adjustable output voltage. For charge management and safety, the IC includes an input P-channel MOSFET ideal diode controller, battery (output) overvoltage protection, reverse charge current protection, PWM soft-start and robust non-overlap control for an all N-channel MOSFET PWM power stage. The device includes AC adapter input current limiting, which maximizes the charge rate for a fixed input power level. An external

LTC4012IUF-1#PBF - Li-Ion, Battery Charger IC
General Description:
The LTC4012 is a constant-current /constant-voltage battery charger controller. It uses a synchronous quasi-constant frequency PWM control architecture that will not generate audib le noise with ceramic bulk capacitors. Charge current is set by external resistors and can be monitored as an output voltage. With no built-in termination, the LTC4012 family charges a wide range of batteries under external control. The LTC4012 features fully adjustable output voltage, while the LTC4012-1 and LTC4012-2 can be pin-programmed for Lithium-Ion/Polymer battery packs of 1-, 2-, 3- or 4-series cells. The LTC4012-1 provides output voltage of 4.1V/cell and the LTC4012-2 is a 4.2V/cell version. The device includes AC adapter input current limiting, which maximizes charge rate for a fixed input power level. An external sense resistor programs the input current limit, and the ICL status pin indic
