Overview
1.1
Introduction
The Integrated Circuits Half Bridge Driver-Switch GS-EVB-HB-0650603B-HD is a demonstration board
containing two HEY1011-L12C GaN FET drivers and two 650V, 60A GaN FETs configured in a half bridge
configuration.
The datasheet for the HEY1011-L12C in this board can be found
The GS-EVB-HB-0650603B-HD can be used to perform
, or to interface the half bridge to
an existing
, both as shown below.
The isolated HEY1011-L12C driver does not require secondary side power or bootstrap components. Gate
drive power is supplied to secondary side from the primary side supply voltage V
DRV
. The amplitude of
the gate drive can be varied by varying V
DRV
between 7 V and 15 V.

= 12V
2.
Link pins EN_PU and EN (if not using external Enable control)
3.
Apply input gate signals, with adequate dead time, to the IN_L and IN_H inputs.
4.
Convenient test points a located on the test board as shown above. A suitable differential
oscilloscope should be used to monitor the high side gate signal from V
