Motor Control Solutions

International Rectifier offers a series of fully integrated Brushless DC Motor Controllers. The product line consists of sensorless controllers, analog controllers and stand-alone power modules in H-bridge, half-bridge and 3-phase configurations. The analog and digital control products pack control circuitry and the power stage in a single, high-density package. Our designs utilize chip and wire and/or PCB (SMT and through-hole) assembly technologies. The high reliability devices are available in a variety of hermetic and plastic packages. No matter what your needs, we can provide cost-effective, application-specific solutions that meet the requirements of the most demanding and rugged environments.

RAD-Hard Motor Drivers

IR also also offers RAD-Hard hybrid motor drivers to address the need for BLDC Motor control in space applications. Typical 3-phase motor driver devices are packaged in a hermetic 32 pin metal can, and are designed to withstand the wide operational temperature range demanded in space applications. Internal to the device is IR’s radiation hardened MOSFETs and gate drivers. These devices support motor bus voltages up to 160 Vdc and is capable of 3.2 amps motor current per phase.

IGBT High Power Multi Chip Modules

IR offers a broad range of standard and custom IGBT modules up to 200 amps as a 3-phase bridge and 600 amps in phase leg configurations. Additional brake chopper and gate protection circuitry can also be included in the module. The latest IGBT and soft recovery diodes are packaged on an isolated substrate and metal base plate with a plastic enclosure. These devices are built and screened in accordance with MIL-PRF-38534 and are designed for use in military, commercial aircraft and electric vehicles where reliability and performance of “Near” hermetic packaging is required. The module meets the industry standard pin configuration, and the power electronics are encapsulated in a proprietary sealing method. The unique sealing method of the power semiconductors includes a conformal coating and epoxy seal that resists moisture even at elevated temperatures. This ability to resist high moisture and temperature, HAST Highly Accelerated Stress Test (HAST) testing, mimics the welded “Hermetic” metal package and is how we have adopted the term “near hermetic” to describe the package.
