Richardson RFPD announced the availability and full design support capabilities for a new single-channel IGBT/MOSFET gate driver from Power Integrations. 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 8 A peak output drive current, the SID1183K can drive devices up to 600 A 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. Provided in a eSOP package with 9.5 mm creepage and clearance distances, additional key features of the SID1183K include up to a 75kHz switching frequency, a low propagation delay time of 260 ns, a propagation delay jitter of +/-5ns, and a -40ºC to 125ºC operating ambient temperature. Controller signals are compatible with 5V CMOS logic, and may be adjusted to 15V levels by using an external resistor divider.
The SID1183K is suitable for a range of applications, including general purpose and servo drives, UPS, solar, welding inverters and power supplies.
