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 10.4×12.5×2.0mm and operates over a temperature range from -40 to +125°C.
Sample shipments of the TB9150FNG started in April, with mass production scheduled for 2018.
