Overview
The STGAP2SCMTR is a galvanically isolated 4 A single gate driver produced by STMicroelectronics. This device provides galvanic isolation between the gate driving channel and the low voltage control and interface circuitry, making it suitable for mid and high power applications such as power conversion and motor driver inverters in industrial settings. The gate driver is characterized by its 4 A capability and rail-to-rail outputs, and it is available in two different configurations to optimize turn-on and turn-off processes using dedicated gate resistors or a Miller CLAMP function to prevent gate spikes in half-bridge topologies.
