Innoscience’s new SolidGaN ISG624x series integrates a half-bridge gate driver, two 700V GaN power FETs, and a bootstrap diode into a single EN‑SOP15 package. Designed specifically for 220V variable-frequency appliance motor drives, the IC shrinks PCB area by 30–50% while simplifying thermal and EMI management.

The family includes five pin‑compatible models covering 1.2A to 11A, suiting motor drives from 30W to 500W. Supply voltage ranges 10–20V, and the built‑in 700V bootstrap diode eliminates multiple external components. The low‑thermal‑resistance EN‑SOP15 package offers 4.2mm creepage for high‑voltage safety, easing appliance certification.

Four key performance gains:

• GaN’s zero reverse‑recovery cuts switching losses by 80% vs. silicon MOSFETs. At similar power, temperature rise drops up to 50°C, removing heatsinks in <500W designs.

• Segmented gate drive controls slew rate at 5V/ns, passing EMI without RC snubbers.

• Built‑in protection includes dual UVLO, 0.45V‑precision overcurrent, 140°C thermal shutdown, 120ns hardware dead‑time, and >50µs short‑circuit tolerance for locked‑rotor conditions.

• 700V rating delivers higher margin than 600‑650V IGBTs, improving reliability under frequent start‑stop and stall events.

Unlike generic half‑bridge GaN parts, the ISG624x is purpose‑built for BLDC motor drives in air conditioners, washing machines, refrigerators, and range hoods. Innoscience already ships over 5 million GaN chips in production with major brands like Midea and Haier.

ICgoodFind Takeaway:
The ISG624x brings GaN performance to cost‑sensitive appliance motor control with fewer parts, smaller boards, and cleaner EMI. A drop‑in upgrade that speeds time‑to‑market.
