Toshiba Electronics Europe has announced an opto-isolated IGBT gate pre-driver IC with enhanced protection functions for the in-vehicle inverters of electric and hybrid vehicles. Sample shipments of the TB9150FNG started in April, with mass production scheduled for 2018.
Inverter control is used to drive the motors of electric and hybrid vehicles efficiently. As the control and drive functions have different operating voltages, they must be isolated from each other with a device such as a photocoupler. Toshiba’s TB9150FNG is a compact, versatile, high-performance IGBT gate pre-driver IC that can address this issue while providing the necessary protection functionality.
The TB9150FNG integrates a photocoupler that secures high-level isolation between control (the primary side) and drive (the secondary side). It also incorporates a highly precise IGBT temperature detection function, a flyback transformer controller and a short circuit detection function (current sense and DESAT2 monitor) that all contribute to system downsizing.
Supplied in an SSOP48 package, the TB9150FNG measures just 10.4mm x 12.5mm x 2.0mm. Operating temperature range is -40°C to 125°C.
