STMicroelectronics adds 100V series to GANSPIN family for compact, efficient motor control

What happened

STMicroelectronics has added a 100V series to its GANSPIN family, providing an easy-to-use gallium nitride (GaN) power stage for building compact and efficient motor drives. The three new 5mm x 6.5mm devices are the GANSPIN1102 with typical RDS(on) of 2.4mΩ, the GANSPIN1102E which adds a dedicated top-side-cooling option for directly removing heat from the package in thermally demanding, high-power-density designs, and the GANSPIN1105 with typical RDS(on) of 5.5mΩ. Continuous output-current capability is stated as up to 60 A depending on the device; each integrates two GaN transistors, gate drivers with optimized gate resistance, and VCC and bootstrap capacitors, and fast 20ns propagation delay with accurate 1ns delay matching permits switching frequencies up to 5MHz. The three devices are supplied in a 1.12mm-high land grid array (LGA) and can operate with junction temperature from -40°C to 125°C. The devices are planned to be available by the end of 2026, priced from $x.xx for orders of 1000 pieces; the source states no price change or capacity change. At electronica 2026 in Munich (November 10-13), visitors can see the GANSPIN1102E driving the joints of a robotic arm in a live demonstration at the ST booth, Hall C3/Booth 101.
