By combining gate drivers, bootstrap diodes, IGBTs/power MOSFETs, fly wheel diodes and protection functions within a HSDIP25 package, ROHM meets the demands of motor driving and inverter applications, which require compactness, high integration and reliability. The IGBTs/IPMs feature an aluminium-based Silicon-on-Isolator technology, which provides enhanced high-voltage capacity, high heat conductivity and low leak current, while preventing latch-up.
The IC features a current limit for the bootstrap diode, under voltage lock-out for floating supply, fault output, thermal shut-down and short circuit protection, as well as a FWD (IGBT version) to eliminate flyback, all of which increase reliability. Suitable motor driving and inverter applications include home appliances such as air conditioners, heat-pumps for washing machines and refrigerators.
