EVALSTGAP1S: demonstration board for STGAP1S galvanically
isolated single gate driver
Introduction
The STGAP1S gapDRIVE™ is a galvanically isolated single gate driver for N-channel
MOSFETs and IGBTs with advanced protection, configuration and diagnostic features. The
architecture of the STGAP1S isolates the channel from the control and the low voltage
interface circuitry through a true galvanic isolation.
The EVALSTGAP1S board allows evaluating all of the STGAP1S features while driving
a power switch with a voltage rating up to 1500 V. Power switches in both TO-220 and
TO-247 packages can be evaluated, and the board allows the connection of a heatsink in
order to exploit the ability of the STGAP1S to handle very high power applications.
In combination with the STEVAL-PCC009V2 communication board and the gapDRIVE™
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.
