LM5051中文资料-6V 至 -100V、690uA IQ 理想二极管控制器数据手册TI规格书

描述 Description

The LM5051 Low Side OR-ing FET Controller operates in conjunction with an external MOSFET as an ideal diode rectifier when connected in series with a power source. This OR-ing controller allows MOSFETs to replace diode rectifiers in power distribution networks thus reducing both power loss and voltage drops.The LM5051 controller provides gate drive for an external N-Channel MOSFET and a fast response comparator to turn off the FET when current flows in the reverse direction. The LM5051 can connect power supplies ranging from -6V to -100V and can withstand transients up to -100V.The LM5051 also provides a FET test diagnostic mode which allows the system controller to test for shorted MOSFETs.
