Description
The STGAP2GS is a single gate driver which provides galvanic isolation between the
gate driving channel and the low voltage control and interface circuitry.
The gate driver is characterized by 2 A source and 3 A sink capability and rail-to-rail
outputs, making the device also suitable for mid and high power applications such as
power conversion and motor driver inverters in industrial applications.
The device allows to independently optimize turn-on and turn-off by using dedicated
gate resistors.
The device integrates protection functions including thermal shutdown and UVLO
with optimized level 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 crossconduction
in case of controller malfunction.
The input to output propagation delay results contained within 45 ns, providing high
PWM control accuracy.
A standby mode is available to reduce idle power consumption.
