ON Semiconductor extends IGBT portfolio

ON Semiconductor has further expanded its portfolio for industrial motor drive applications with a number of new IGBT power modules.

Among a number of announcement the company has unveiled the NXH25C120L2C2, NXH35C120L2C2/2C2E, and NXH50C120L2C2E, which are 25, 35, and 50 Ampere versions of Transfer-Molded Power Integrated Modules (TM-PIM) for 1200V 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 - CIB versions use an additional 1200V IGBT coupled with a diode. The modules feature transfer-moulded encapsulation, extending the cycling lifetime for both temperature and power and measure just 73 x 40 x 8 mm, have solderable pins, and have a standardized pin-out for CIB and CI versions.

The company has also launched 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 75 A.

According to the company, 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 2500 Vrms / minute.

On-chip galvanic isolation means that the NCD57000 and NCD57001 IGBT Gate Drivers deliver more efficient, reliable gate driver designs by reducing system complexity. The devices deliver 4/6 A of source and sink current respectively, while integrating DESAT, Miller clamp, UVLO, Enable, and regulated VREF.

The NCS21871 zero-drift operational amplifier provides precision signal conditioning with a low input offset voltage of 45 µV, and is able to maintain that level of precision from -40°C to +125°C with low input offset drift of 0.4 µV/°C. These parameters make it suitable for low-side current sensing.

The NCP730 LDO Regulator delivers 150 mA with ±1% output voltage accuracy, and has an operating input voltage range of 2.7 to 38 V with low dropout. The integrated soft-start to suppress inrush current, and short-circuit and over-temperature protections for overload conditions means they can be used in industrial automation applications.
