STMicroelectronics EVALSTGAP1BS Demonstration Board

STMicroelectronics EVALSTGAP1BS Demonstration Board is based on the STGAP1B1S galvanically isolated single gate driver for N-channel MOSFETs and IGBTs with advanced protection, configuration, and diagnostic features. Through true galvanic isolation, the STGAP1B1S architecture separates the channel from the control and the low-voltage interface circuitry.

The STMicro EVALSTGAP1BS demo board evaluates all of the STGAP1B1S features while driving a power switch with a voltage rating of up to 1500V. Power switches in both TO-220 or TO-247 packages can be evaluated, and the board facilitates the connection of a heatsink to exploit the ability of the STGAP1B1S to handle very high-power applications.

Combined with the STEVAL-PCC009V2 communication board and the STGAP1B1S evaluation software, the board can easily enable, configure, or disable 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.

Multiple boards can be connected and share the same logic supply voltage and control signals to evaluate half-bridge, interleaved, or even more complex topologies. The board allows the implementation of the SPI daisy chain when more than one device is used.
