Product overview
Description
The STDRIVE631P is a high-voltage device that extends the STDRIVE product family. It integrates three half-bridge gate drivers for N-channel power MOSFETs and IGBTs. The device is suitable for three-phase applications.
All device outputs can sink and source 1.0 A and 0.85 A respectively. Prevention from cross conduction is ensured by interlocking and deadtime function.
The device has dedicated input pins for each output and a shutdown pin. The logic inputs are CMOS/TTL compatible down to 3.3 V for easy interfacing with control devices. Matched delays between low-side and high-side sections guarantee no cycle distortion and allow high frequency operation.
The STDRIVE631P embeds a comparator featuring advanced SmartSD function also integrated in the device, ensuring fast and effective protection against fault events like overcurrent, overtemperature, etc.
Dedicated UVLO protection on the low-sides and each of the high-side driving sections prevents the power switches from operating in low efficiency or dangerous conditions.
The integrated bootstrap diodes as well as all of the integrated features of this IC make the application PCB design easier, more compact and simpler, thus reducing the overall bill of material.
The device is available in SO-28 package.
