Product overview
Description
The STDRIVEG611 is a high-voltage half-bridge gate driver for N‑channel Enhancement Mode GaN.
The high-side driver section is designed to stand a voltage rail up to 600 V and can be easily supplied by the integrated bootstrap diode.
High current capability, short propagation delay with excellent delay matching, and integrated LDOs make the STDRIVEG611 optimized for driving high-speed GaN.
The STDRIVEG611 features supply UVLOs tailored to hard switching applications, interlocking to avoid cross-conduction conditions and an overcurrent comparator with SmartSD.
The input pins extended range allows easy interfacing with controllers. A standby pin allows to reduce the power consumption during inactive periods or burst mode.
The STDRIVEG611 operates in the industrial temperature range, -40 °C to 125 °C.
The device is available in a compact QFN 4x5x1 mm package with 0.5 mm pitch.
