ON Semiconductor has expanded its portfolio for industrial motor drive applications. ON Semiconductor announced the NXH25C120L2C2, NXH35C120L2C2/2C2E, and NXH50C120L2C2E, which are 25, 35, and 50 Ampere versions of Transfer-Molded Power Integrated Modules (TM-PIM) for 1200 Volt (V) applications. They are available in Converter-Inverter-Brake (CIB) and Converter-Inverter (CI) configurations.
The modules consist of six 1200V IGBTs, six 1600V rectifiers, and an NTC thermistor for system level temperature monitoring; the CIB versions use an additional 1200 V IGBT coupled with a diode. The new modules feature transfer-molded encapsulation, extending the cycling lifetime for both temperature and power. The modules measure just 73mm x 40mm x 8mm, have solderable pins and have a standardized pin-out for CIB and CI versions.
The company also announced the NFAM2012L5B and NFAL5065L4B, expanding its Intelligent Power Module (IPM) portfolio, which includes voltage ratings of 650V and 1200V, and current ratings from 10 to 75A. These 3-phase inverters—with integrated short circuit rated Trench IGBTs, fast recovery diode, gate driver, bootstrap circuits, optional NTC thermistor, and protection – provide compact, reliable modules with UL 1557 certification via an isolation rating of 2500Vrms / minute. These IPMs feature direct bonding copper substrate and low loss silicon, enhancing power cycling lifetime and thermal dissipation.
With on-chip galvanic isolation, the NCD57000 and NCD57001 IGBT Gate Drivers enable compact, efficient, reliable gate driver designs by reducing system complexity. The devices deliver 4A/ 6A of source and sink current respectively, while also integrating DESAT, Miller clamp, UVLO, Enable, and regulated VREF.
The NCS21871 zero-drift operational amplifier, which provides precision signal conditioning with a low input offset voltage of 45µV, and maintains that precision from -40°C to +125°C with low input offset drift of 0.4µV/°C. These parameters make it ideal for low-side current sensing.
The NCP730 LDO Regulator delivers 150mA with ±1% output voltage accuracy, and has an operating input voltage range of 2.7 to 38V with low dropout. The integrated soft-start to suppress inrush current, and short-circuit and over-temperature protections for overload conditions, make the device ideal for industrial automation applications.
