STDRIVE601 Triple Half-Bridge High-Voltage Gate Dr

STMicroelectronics' STDRIVE601 is a high-voltage device manufactured with BCD6s offline technology. It 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 350 mA and 200 mA 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 STDRIVE601 embeds a comparator featuring advanced SmartSD function also integrated into 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 allow the device to prevent the power switches from operating in low efficiency or dangerous conditions.

The integrated bootstrap diodes, as well as all the integrated features of this IC, make the application PCB design easier, more compact and simple thus reducing the overall bill of material. The device is available in an SO-28 package.
