STMicroelectronics STGAP2GSN Isolated 3A Single Gate Driver

STMicroelectronics STGAP2GSN Isolated 3A Single Gate Driver isolates the gate driving channel, low voltage control, and interface circuitry. The gate driver is characterized by 2A source and 3A sink capability and rail-to-rail outputs, making the device suitable for mid and high-power applications such as power conversion and motor driver inverters in industrial applications. The device allows independently optimized turn-on and turn-off by using dedicated gate resistors.

The STMicroelectronics STGAP2GSN integrates protection functions, including thermal shutdown and UVLO, with optimized levels for Enhancement-mode GaN FETs, which enables easy design, high efficiency, and reliable systems. Dual input pins allow the selection of signal polarity control and implementation of HW interlocking protection to avoid cross-conduction in case of a controller malfunction. The input-to-output propagation delay results are contained within 45ns, providing high PWM control accuracy. A standby mode is available to reduce idle power consumption.
