Power Integrations SID1183K single-channel IGBT/MOSFET gate driver

Power Integrations’ SID1183K is a single-channel IGBT and MOSFET gate driver in an eSOP package with 9.5 mm creepage and clearance distances. Galvanic isolation is provided by the company’s innovative solid insulator FluxLink technology.

With up to 8 A peak output drive current, the product can drive devices up to 600 A without requiring additional active components. For gate drive requirements that exceed the standalone capability of the device, an external booster may be added. Stable positive and negative voltages for gate control are provided by one unipolar isolated voltage source.

The driver includes short-circuit protection (DESAT) with advanced soft shutdown (ASSD), as well as undervoltage lockout (UVLO) for the primary and secondary side. Rail-to-rail output with temperature- and process-compensated output impedance ensure safe operation even in harsh conditions.

Additional features include: up to 75 kHz switching frequency; low propagation delay time of 260 ns; propagation delay jitter of ±5 ns; and operating ambient temperature of -40 to +125°C. Controller signals are compatible with 5 V CMOS logic and may be adjusted to 15 V levels by using an external resistor divider.

The product is suitable for a range of applications, including general-purpose and servo drives, UPS, solar, welding inverters and power supplies.
