High-performance power modules for industrial motor drives up to 4kW

Infineon Technologies AG has expanded its 7th generation TRENCHSTOP IGBT7 product family with the CIPOS Maxi Intelligent Power Module (IPM) series for low-power motor drives. The new IM12BxxxC1 series is based on the new TRENCHSTOP IGBT7 1200V and rapid diode EmCon 7 technology. Thanks to the latest micro-pattern trench design, it provides excellent control and performance. This results in notable loss reduction, improved efficiency, and higher power density. The portfolio includes three new products in variants ranging from 10A to 20A for power ratings of up to 4kW: IM12B10CC1, IM12B15CC1 and IM12B20EC1.

The series is packaged in a DIP 36x23D housing. It incorporates various power and control components to improve reliability, optimise PCB size and reduce system costs. This makes it the smallest package for 1200V IPMs with the highest power density and best performance in its class. The series is particularly suited for low-power drives in applications such as motors, pumps, fans, heat pumps and outdoor fans for heating, ventilation, and air conditioning.

The new IPM series provides an isolated dual-in-line moulded housing for exceptional thermal performance and electrical isolation. It also satisfies the EMI and overload protection needs of demanding designs. In addition to the protection features, the IPM is equipped with an independent UL-certified temperature thermistor. The CIPOS Maxi integrates a rugged six-channel SOI gate driver to supply built-in dead time and prevent transients' damage. It features an under-voltage lockout at all channels and an over-current shutdown. With its multi-function pin, this IPM permits high design flexibility for various purposes. The low-side emitter pins can be accessed for all phase current monitoring, making the device easy to control.
