IR25750LPBF TM HVIC SOT-23 Current Sensing IC Features Description VDS(on) or VCE(on) sensing Eliminates external current sensing resistors The IR25750L is a novel current sensing IC that Enables inductance-less current sensing extracts the VDS(on) of a power MOSFET, or the VCE(on) of an IGBT, during the switch on-time. 600V blocking capability IRs proprietary 600V HVIC technology then Programmability and temperature compensation possible blocks the high drain voltage to during the No VCC required MOSFET or IGBT off-time. This IC allows for Gate drive on/off sync input external current sensing resistors to be eliminated Filter delay at GATE turn-on (200nsec typ.) for reducing power losses and increasing overall 20.8V zener clamps on GATE and CS pins system efficiency. The IC includes a gate drive Integrated ESD protection and latch immunity on all pins input that provides VCC supply voltage to the IC Tiny 5-pin SOT-23 package and synchronizes the internal sensing circuit to the on and off times of the switch. Programmability and temperature compensation Applications are also possible. MOSFET, DirectFET, or IGBT current sensing Over-current protection Industrial applications Package Options Motor control Power tools Brick converters Forklifts 5 Lead SOT 23 Induction heating Typical Connection Diagram Ordering Information Standard Pack Base Part Number Package Type Orderable Part Number Form Quantity IR25750LPBF SOT23-5L Tape and Reel 3000 IR25750LTRPBF 1 www.irf.com 2015 International Rectifier January 15, 2015 IR25750LPBF Table of Contents Page Description 1 Ordering Information 1 Typical Connection Diagram 1 Absolute Maximum Ratings 3 Recommended Operating Conditions 3 Electrical Characteristics 4 Functional Block Diagram 5 Timing Diagram 6 Pin Definitions 7 Pin Assignments 7 Input / Output Pin Equivalent Circuit Diagrams 8 Functional Description 9 Package Details: 5L SOT-23 13 Tape and Reel Details: 5L SOT-23 14 Part Marking Information 16 Qualification Information 17 2 www.irf.com 2015 International Rectifier January 15, 2015
