STMicroelectronics MASTERGAN family

MasterGaN1/2/3/4/5 are advanced power Systems-in-Package (SiP), integrating a gate driver and two enhancement-mode GaN power transistors in (asymmetrical for MasterGan2 and 3) half-bridge configuration.

The integrated power GaNs have 650 V drain-source blocking voltage and R_DS(ON) from 150 mΩ to 450 mΩ (depending on MasterGaN version), while the integrated bootstrap diode can easily supply the high side of the embedded gate driver.

The MasterGaN family features UVLO protection on both the lower and upper driving sections, preventing the power switches from operating in low efficiency or dangerous conditions and the interlocking function.

Key features

• QFN 9 x 9 x 1 mm package
• R_DS(ON) from 150 mΩ to 450 mΩ
• I_DS(MAX) from 4 A to 10 A
• UVLO protection on low-side and high-side
