600V Half Bridge Drivers Sink/Source up to 4A
STMicroelectronics' new STDRIVE family of half-bridge MOSFET and IGBT gate drivers are designed to operate in harsh industrial environments withstanding high voltages up to 600V, while maintaining good noise immunity and low switching losses.
ST’s high-voltage drivers are designed to optimize vector motor drive systems and feature excellent performance at high switching frequency and smart shutdown to protect the final application.
The smartDRIVE™ IGTB and MOSFET drivers integrate a comparator for protection, an operational amplifier for current sensing and an integrated bootstrap diode, thus reducing the number of external components required at system level.
L6491, L6494, and L6498 high-voltage half-bridge gate drivers are particularly-suited for medium- and high-capacity power switches thanks to their sink/source current capability up to 4A.
An integrated bootstrap diode and comparator for fast protection against over-current and over-temperature conditions, as well as an independent UVLO protection circuit, make the application's PCB design simpler and more compact in addition to helping to reduce the overall bill of material.
