The EVALSTGAP1BS is a galvanically isolated single gate driver for N-channel MOSFETs and IGBTs with advanced protection, configuration and diagnostic features. The architecture of the STGAP1B1S isolates the channel from the control and the low voltage interface circuitry through true galvanic isolation.


The EVALSTGAP1B1S board allows evaluating all of the STGAP1B1S features while driving a power switch with a voltage rating up to 1500 V. Power switches in both TO-220 or TO-247 packages can be evaluated, and the board allows the connection of a heatsink in order to exploit the ability of the STGAP1B1S to handle very high power applications.


In combination with the STEVAL-PCC009V2 communication board and the STGAP1B1S evaluation software, 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.


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