Family: RAJ280003 is 2. 5mohm single channel Intelligent Power Devices (IPD) embedded in TO263-7 package. It is N-channel high-side switches with charge pump, diagnostic feedback with proportional load current sense and embedded protection function. Family includes up to 4 devices depending on on-state resistance, input interface combination between current driven and voltage driven. Scalability: Variety of on-state resistance combined with standardized package on pin-out give user high flexibility for unit design depending on target load. Robustness: Because of advanced protection method, RAJ280003 achieves high robustness against long term and repetitive short circuit condition.


  • Built-in charge pump
