EVAL6393FB

Low voltage full bridge reference design board featuring L6393 advanced high-voltage gate driver
  • active Active

The EVAL6393FB demonstrates how to use two L6393 drivers to drive a single-phase load through a full-bridge topology. This allows both the direction and the value of the current flowing into the load to be controlled. Typical loads, which can be effectively driven by using this topology, are single-phase BLDC motors, fans and HID lamps. Thanks to the integrated features of the L6393, the board has a very small footprint and an optimized layout, and can be simply run by applying the BUS voltage and a direction signal.
