ON Semiconductor has expanded its portfolio for industrial motor drive applications, addressing the need for energy efficiency, precise measurement, accurate control, and high reliability in harsh industrial environments. These devices also feature the integration of active and passive components and advanced packaging, including substrate materials.
Here are the latest additions:
The NXH25C120L2C2, NXH35C120L2C2/2C2E, and NXH50C120L2C2E, are 25-, 35-, and 50-A versions, respectively, of transfer-molded power integrated modules (TM-PIM ) for 1,200-V applications. Available in converter-inverter-brake (CIB) and converter-inverter (CI) configurations, the modules consist of six 1,200-V IGBTs, six 1,600-V rectifiers, and an NTC thermistor for system-level temperature monitoring. The CIB versions use an additional 1,200-V IGBT coupled with a diode. Featuring transfer-molded encapsulation, these modules offer extended cycling lifetime for both temperature and power. The modules measure 73 × 40 × 8 mm, with solderable pins and a standardized pin-out for CIB and CI versions.
The NFAM2012L5B and NFAL5065L4B devices, which expand the company’s intelligent power module (IPM ) portfolio, includes voltage ratings of 650 V and 1,200 V and current ratings from 10 to 75 A. These three-phase inverters — with integrated short-circuit–rated trench IGBTs, a fast recovery diode, gate driver, bootstrap circuits, optional NTC thermistor, and protection — provide UL 1557 certification via an isolation rating of 2,500 Vrms/minute. These IPMs feature a direct bonding copper substrate and low-loss silicon, which improves power-cycling lifetime and thermal dissipation.
With on-chip galvanic isolation, the NCD57000 and NCD57001 IGBT gate drivers reduce system complexity, integrating the DESAT, Miller clamp, UVLO, enable, and regulated VREF. The devices deliver 4/6 A of source and sink current, respectively.
Suited for low-side current sensing, the NCS21871 zero-drift operational amplifier provides precision signal conditioning with a low input offset voltage of 45 µV. The device maintains that precision over a temperature range of –40°C to 125°C, with a low input offset drift of 0.4 µV/°C.
The NCP730 LDO regulator offers 150 mA with ±1% output voltage accuracy and has an operating input voltage range of 2.7 to 38 V with low dropout. Featuring an integrated soft-start to suppress inrush current and short-circuit and overtemperature protections for overload conditions, this device targets industrial automation applications.
