Description
The EVALSTGAP4S is a galvanically isolated single gate driver for IGBTs and SiC MOSFETs with advanced protection, configuration, and diagnostic features. The architecture of the STGAP4S isolates the channel gate driving from the control and the low voltage interface circuitry through a true galvanic isolation.The EVALSTGAP4S board allows evaluating all the STGAP4S features while driving a power switch with a voltage rating up to 650 V. The board is provided with two SiC MOSFETs in a H2PAK-7 package connected in half-bridge configuration. The two STGAP4S drivers are connected in an SPI daisy chain and the high voltage side of each is fed by its own flyback power supply, whose controller is integrated in the driver.Multiple boards can be connected and share the same logic supply voltage in order to evaluate complex topologies, such as full-bridge inverter. The connection of multiple boards allows the implementation of the SPI daisy chain with more than two devices.In combination with the STEVAL-PCC009V2 and STSW-STGAP4 GUI, the board allows to easily enable, configure, or disable all of the driver's protection and control features through the SPI interface. Advanced diagnostic is also available thanks to the driver's status registers that can be accessed through the SPI.
