Technical details

Isolated gate driver with 4 A peak drive and 3000 Vrms isolation

It delivers 4 A peak output current with 3000 Vrms isolation, making it a fit for driving power switches in motor drives, inverters, and switched-mode power supplies where galvanic isolation between the controller and the power stage is required.

Maximum propagation delay is 68 ns for both low-to-high and high-to-low transitions. That number sets the lower bound on dead-time you can program in the PWM controller — too tight and you risk shoot-through. The 12 ns typical rise and fall time keeps the gate drive edges crisp, which helps reduce switching losses in the power FETs or IGBTs.

Package and approvals

Housed in an 8-SOIC narrow-body package (3.90 mm width), surface-mount. Safety approvals include CSA, UR, and VDE — the marks that matter when the end equipment must pass IEC 62368-1 or UL 61800-5-1 for motor drives.
