SID1182K
Power Integrations SID1182K SCALE-iDriver single-channel gate driver IC, 8 A peak, 1200 V, reinforced FluxLink isolation in eSOP-R16B.
The SID1182K is a Power Integrations SCALE-iDriver single-channel, galvanically isolated IGBT and MOSFET gate driver IC rated up to 1200 V with a peak output current of 8 A, in the compact eSOP-R16B surface-mount package. Reinforced galvanic isolation is provided by Power Integrations' FluxLink solid-insulator technology, so the driver needs no optocoupler and its timing is stable and free of the aging that affects optocouplers. The 8 A peak output drives IGBTs with nominal currents up to about 600 A without an external booster, and where a larger module needs more gate current an external amplifier can be added. A single unipolar insulated supply generates the stable positive and negative gate voltages, which simplifies the power architecture and reduces the number of isolated supplies. Integrated protection includes short-circuit detection with advanced soft shutdown, primary-side and secondary-side undervoltage lockout, and rail-to-rail output with temperature- and process-compensated impedance, which keep the driver safe in harsh conditions. The maximum switching frequency is 250 kHz, so the part suits high-frequency converters as well as general drives. Typical applications include motor and servo drives, solar inverters, UPS, welding inverters and power supplies. Every driver BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file.
FAE Professional Review
The SID1182K is the part we recommend when a design needs a compact, isolated gate driver with strong protection and minimal external circuitry. Its 8 A peak output and 250 kHz capability cover the majority of industrial drives and solar stages, and the FluxLink isolation removes the optocoupler reliability concern. Set the separate turn-on and turn-off gate resistors for your module, and follow the recommended isolation clearance.

Frequently Asked Questions
What projects suit the SID1182K?
It suits motor and servo drives, solar inverters, UPS and welding inverters that need a compact, isolated gate driver with integrated protection. The 8 A peak output drives IGBTs up to about 600 A, and 250 kHz switching suits high-frequency designs.
For smaller modules or a lower-cost build, the SID1152K or SID1132K may be sufficient.
What protection features does it include?
It includes short-circuit detection with advanced soft shutdown, and undervoltage lockout on both the primary and secondary sides, plus rail-to-rail output with compensated impedance. These features keep the IGBT and the driver safe during faults and supply dips.
