LTC4000IGN-1#PBF

LINEAR TECHNOLOGY  LTC4000IGN-1#PBF  芯片, 控制器, 充电, 3/60V输入, 1%CC, 28SSOP

The is a high voltage, high current Controller for battery charging. The high performance controller that converts many externally compensated DC/DC power supplies into full-featured battery chargers. It supports intelligent PowerPath control. An external PFET provides low loss reverse current protection. Another external PFET provides low loss charging or discharging of the battery. This second PFET also facilitates an instant-on feature that provides immediate downstream system power even when connected to a heavily discharged or short faulted battery.
