STMicroelectronics GANSPIN612 Half-Bridge GaN Motor Driver

STMicroelectronics GANSPIN612 Half-Bridge GaN Motor Driver is an advanced power system-in-package (SiP) integrating two enhancement mode GaN transistors in a half-bridge configuration driven by a state-of-the-art high-voltage, high-frequency gate driver. The integrated power GaNs have RDS(ON) of 270mΩ and a 650V drain-source breakdown voltage, while the integrated bootstrap diode can easily supply the high-side of the embedded gate driver.

Designed for motion control, the GANSPIN612 optimizes the output dV/dt to 10V/ns (typ.) for both hard-on and hard-off. This feature is required in motor control for EMI, motor winding, and ball bearing reliability. The GANSPIN612 is available in a compact 9mm x 9mm x 1mm QFN package and operates over the industrial temperature range of -40°C to +125°C.

The STMicroelectronics GaNSPIN612 is pin-to-pin compatible with GaNSPIN611 [RDS(ON) of 138mΩ] to maximize scalability within a platform approach.
