Availability and full design support capabilities for a new single-channel IGBT/MOSFET gate driver from Power Integrations has been announced by Richardson RFPD. The SID1183K is a single-channel IGBT and MOSFET driver in an eSOP package. Galvanic isolation is provided by Power Integrations’ innovative solid insulator FluxLink technology

With up to 8A peak output drive current, the SID1183K can drive devices up to 600A without requiring additional active components.

For gate drive requirements that exceed the stand-alone capability of the SID1183K, an external booster may be added.

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

The new driver includes short-circuit protection (DESAT) with advanced soft shut-down (ASSD), as well as undervoltage-lockout (UVLO) for primary-side and secondary-side.

Rail-to-rail output with temperature- and process-compensated output impedance guarantee safe operation even in harsh conditions. 

The SID1183K is suitable for a range of applications, including general purpose and servo drives, UPS, solar, welding inverters and power supplies. 

Additional key features of the SID1183K include up to 75kHz switching frequency, low propagation delay time of 260ns, -40o C to 125oC operating ambient temperature.
