The STDRIVE601 is a high voltage devicemanufactured with BCD6s offline technology. It isa single-chip with three half-bridge gate drivers forN-channel power MOSFETs or IGBTs suitable for3-phase applications.
All device outputs can sink and source 350 mAand 200 mA respectively. Prevention from crossconduction is ensured by interlocking anddeadtime function.
The device has dedicated input pins for eachoutput and a shutdown pin. The logic inputs areCMOS/TTL compatible down to 3.3 V for easyinterfacing with control devices. Matched delaysbetween low-side and high-side sectionsguarantee no cycle distortion and allow highfrequency
The STDRIVE601 embeds a comparatorfeaturing advanced SmartSD function also integrated in the device, ensuring fast andeffective protection against fault events like overcurrent, overtemperature, etc.
Dedicated UVLO protection on the low-sides andeach of the high-side driving sections allow toprevent the power switches from operating in lowefficiency or dangerous conditions.
The integrated bootstrap diodes as well as all ofthe integrated features of this IC make theapplication PCB design easier, more compact andsimple thus reducing the overall bill of material.
The device is available in SO-28 package.
