GaNSense Half-Bridge IC – Loss-less current sensing

GaNSense Half-bridge ICs integration of lossless current sensing eliminates external current sensing resistors to increase system efficiency and reduce PCB footprint, eliminate RCS hot-spots.

When comparing GaNSense technology versus existing external current sensing resistor method, the total ON-resistance, RON(TOT), can be substantially reduced. For a 65 W, high-frequency ACF circuit, for example, RON(TOT) is reduced from 320 mW to 160 mW. The power loss savings by eliminating the external resistor results in a +0.5% efficiency benefit for the overall system.
