Overview of 650V EcoGaN™ Power Stage ICs (BM3G015MUV-LB, BM3G007MUV-LB)
The BM3G0xxMUV-LB series of power stage ICs incorporates ROHM's 650V EcoGaN™ together with a dedicated gate driver thatmaximizes performance as well as additional functions and peripherals. The integrated design facilitates replacement of silicon
power semiconductor circuits in primary power supplies.

Features・Power stage circuit ICs simplify mounting of GaN devices
Combines a 650V EcoGaN™, dedicated gate driver, additional functions, and peripheral components in a single package

・Makes it easy to replace existing power semiconductor circuits
2.5V to 30V drive voltage range, 15µs (Typ) startup time, 11ns to 15ns propagation delay

・Low loss vs general products contributes to smaller sets
20% lower power loss, and built-in peripherals reduce the number of external parts from eight to just one
