STMicroelectronics STDRIVE601 Triple Half-Bridge Gate Driver

STMicroelectronics STDRIVE601 Triple Half-Bridge Gate Driver is a high voltage device manufactured with BCD6s offline technology. The device is a single-chip with three half-bridge gate drivers for N-channel power MOSFETs or IGBTs suitable for 3-phase applications. All device outputs can sink and source 350mA and 200mA 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 3.3V 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 STDRIVE601 embeds a comparator featuring an advanced SmartSD function that is also integrated into the device, ensuring fast and effective protection against fault events like overcurrent, overtemperature, etc. Dedicated UVLO protection on the low side 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. These features also make it more compact and simple, thus reducing the overall bill of material (BOM).
