Infineon’s CIPOS Micro IPM adds IGBT based IM231 series

Infineon is introducing its CIPOS Micro IM231 series, a family of 600 V rated intelligent power modules (IPM).

The series is qualified for harsh humid environments, passing 1000 hours of high voltage, high temperature and high humidity reverse bias (HV H3TRB) stress testing.

The CIPOS Micro IM231 series features the latest motor drive TRENCHSTOP 6 IGBT and optimised switching characteristics for higher efficiency and low EMI.

According to Infineon, with 2 kV, this IPM offers the highest UL1557-certified isolation voltage in its class. The series comprises 4 A (IM231-M6S1B, IM231-M6T2B) and 6 A (IM231-L6S1B, IM231-L6T2B) offerings.

For best fit, CIPOS Micro IM231 is offered in both, through-hole (THD) and surface mount (SMD) form factors. Built-in UL certified NTC thermistor, anti-shoot through and accurate over current protection and fault reporting features provide for a smarter system design. The IPM can be implemented in applications with or without heatsink, pushing power up to 450 W.

The new IM231 series offers performance, ruggedness, protection, and ease of use, continues Infineon. The anti shoot-through prevents spurious simultaneous turn on of high and low side IGBTs caused by malfunction of the microcontroller or external noise. In addition, the integrated current protection has a high accuracy of +/-5 per cent. Above that, multiple markets ranging from 100 to 230 V AC can be addressed with the same IPM package and an identical PCB design.
