ROHM Semiconductor has introduced a new series of Intelligent Power Modules (IPM) optimized for high-speed and energy-efficient operation in motor drive and inverter applications.
The 600V module integrates a series of components in a compact package, such as gate drivers, bootstrap diodes, IGBT or ROHM's proprietary low Ron SuperJunction power MOSFET (PrestoMOS) and flywheel diode (FWD). It occupies a small area and has comprehensive protection functions. This kind of setting especially provides a variety of cost-effective design solutions for developers of white goods and industrial motors. The full range of products includes 1.5A, 2.5A, 10A, 15A, 20A and 30A versions with different currents.
The application of the built-in motor driver needs to be highly integrated, compact and reliable, and must withstand harsh environments for a long time. To meet this demand, Rohm has developed high-performance IPM series, including high-side and low-side gate drivers, bootstrap diodes for fast recovery, low saturation 600V IGBT or power MOSFET (PrestoMOS), low Vf and high-speed trr Wait for multiple components flywheel diode (IGBT version) and various protection functions in a compact HSDIP25 package.
The new series utilizes many proprietary technologies and material enhancements to promote current monitoring, heat dissipation and reliable operation. It significantly reduces the power loss during light load and heavy load, while increasing the power capacity. The module uses innovative aluminum-based silicon-on-insulator (SOI) technology to provide enhanced high-voltage capacity, high thermal conductivity, low leakage current, and simultaneously prevent latch-up. For excellent reliability, the IC also has a comprehensive range of protection attributes, such as the current limit of the bootstrap diode, undervoltage lockout for floating power supplies, fault output, thermal shutdown and short circuit protection, and FWD (IGBT version) To eliminate backlash.
