Gate driver device family range from 2.5A to 8A

The SCALE-iDriver family of integrated circuits from Power Integrations is available at Richardson RFPD along with full design support capabilities. The new ICs are galvanically-isolated single-channel gate driver devices that range in output current from 2.5A to 8A, the industry’s highest output current without an external booster.

The SID11x2K devices consist of a single-channel IGBT and MOSFET driver in an eSOP package.

Reinforced galvanic isolation is provided by Power Integrations’ innovative solid insulator FluxLink technology.

The up-to-8A peak output drive current enables the product to drive devices up to 450A (typical) without requiring any additional active components.

For gate drive requirements that exceed the stand-alone capability of the SID1182Ks, an external amplifier (booster) may be added.

Stable positive and negative voltages for gate control are provided by one unipolar isolated voltage source. 

Additional features such as short-circuit protection (DESAT) with advanced soft shutdown (ASSD), undervoltage lockout (UVLO) for primary-side and secondary-side, and rail-to-rail output with temperature- and process-compensated output impedance guarantee safe operation even in harsh conditions.

The family of consists of a 2.5A device, 5A device and 8A device. They are suitable for 600 V, 650 V, 1200 V IGBT and MOSFET switches and offer up to 250kHz switching frequency. They have a low propagation delay time: 260 ns and propagation delay jitter is +/-5ns.

The devices, which operate at between -40°C to 125°C operating ambient temperature, have high common-mode transient immunity and come in an eSOP package with 9.5mm creepage and clearance
