International Rectifier Intros New iMOTION Line IPMs
International Rectifier Corp. (IR, El Segundo, CA) introduced a set of 600 V, 16 A and 20 A integrated power modules (IPMs), the IRAMY20UP60B, IRAMX20UP60A and IRAMX16UP60B, which are part of the iMOTION™ integrated design platform. Designed for 85 Vac to 253 Vac variable speed motor drives, the new IPMs integrate IR's proprietary high-voltage integrated circuit (HVIC) with a three-phase inverter power stage. The 16 A device addresses the 750 W to 1.2 kW power range while the 20 A devices can accommodate 750 W to 2.2 kW.
The IRAMY20UP60B is a 20 A, 600 V IPM with an internal shunt resistor that combines low VCE(on) non-punch-through and short-circuit-rated IGBT technology with IR's three-phase HVIC gate driver. The IPM has a built-in temperature monitor. The integrated HVIC enables over-current and over-temperature protection, as well as under-voltage lockout, delivering high levels of protection for fail-safe operation.
The IRAMX20UP60A is a 20 A, 600 V IPM that does not include a shunt resistor, but is packaged in a compact SIP2 outline. An open emitter configuration of the low-side IGBT switches offer easy current feedback and over-current monitoring for high precision and reliable control. The IRAMX16UP60B, offering similar functions and features to its 20 A counterparts, is rated at 16 A for motors in the 750 W to 1.2 kW power range. The IRAMX16UP60B also comes in the SIP2 package, includes internal shunt resistor, temperature monitor and all the safe-fail features of the IRAM product family.
Samples of the IRAMX16UP60B, IRAMX20UP60A and IRAMY20UP60B are now available, and delivery for production quantity is eight weeks ARO. Pricing starts from $10.95 each in 10,000-unit quantities.
