Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

1ED3431MU12M is Single-channel 5.7 kV (rms) isolated gate driver IC with adjustable DESAT and soft-off. It consists of galvanically isolated single channel gate driver ICs in a small PG-DSO-16 package with a large creepage and clearance of 8 mm. The gate driver ICs provide a typical peak output current of 3 A, 6 A, and 9 A.
