STMicroelectronics MASTERGAN2

The MASTERGAN2 is an advanced power system-in-package integrating a gate driver and two enhancement-mode GaN transistors in an asymmetrical half‑bridge configuration. The integrated power GaNs have 650 V drain‑source breakdown voltage and R_DS(ON) of 150 mΩ and 225 mΩ for Low side and High side respectively, while the high side of the embedded gate driver can be easily supplied by the integrated bootstrap diode, while the high side of the embedded gate driver can be easily supplied by the integrated bootstrap diode.

Key features

• Compact size: QFN 9 x 9 x 1 mm package
• Low R_DS(ON): 150 mΩ (LS) + 225 mΩ (HS)
• I_DS (max) = 10 A (LS) + 6.5 A (HS)

Applications

The EVALMASTERGAN2 demonstration board for MASTERGAN2 high power density half-bridge high voltage driver with two 650 V enhanced-mode GaN HEMT:

• The EVALMASTERGAN2 board is an easy-to-use and quick-to-adapt tool to evaluate the characteristics of MASTERGAN2 and to quickly create new topologies without the need for a complete PCB design. 
• The EVALMASTERGAN2 provides an on-board programmable inputs deadtime generator with a single VCC supply (typ. 6 V). An embedded Linear voltage regulator offers a 3.3 V rail to supply low voltage logic circuits like microcontrollers or FPGAs.
• Some spare footprint is also included to customize the board to operate with the final application. These customizations include the use of a separate input signal or a single PVM signal, the use of an external bootstrap diode, a separate supply for VCC, PVCC, or Vbo, and also the use of a low-side shunt resistor for peak current mode topologies.
• All MASTERGAN2 pins are accessible.
• The EVALMASTERGAN2 is 56 x 70 mm wide, FR-4 PCB resulting in an R_th(J-A) of 35 °C/W, without forced airflow.
