The SCALE-iDriver™ Family of gate driver ICs are single-channel IGBT and MOSFET drivers in a standard eSOP package. Reinforced galvanic isolation is delivered using Power Integrations’ innovative solid insulator FluxLink™ technology. Output drive current up to 8 A (peak) enables the product to drive devices up to 450 A (typical) without requiring any additional active components. For higher current switching semiconductors, where the required gate current exceeds the SCALE-iDriver’s stand alone capabilities, an external amplifier (booster) may be added. Stable positive and negative voltages for gate control are provided by one unipolar insulated voltage source.

Additional features such as short-circuit protection (DESAT) with advanced soft shut down (ASSD), undervoltage lock-out (UVLO) for primary-side / secondary-side and rail-to-rail output with temperature and process compensated output impedance guarantee safe operation even in harsh conditions. Controller (PWM and fault) signals are compatible with 5 V CMOS logic, which may be adjusted to 15 V levels by using external resistor divider.
