High-Power H-Bridge Automotive Valve Driver / Tester

This controller makes use of the latest  FPGA technology to offer unprecedented control and sampling performances as required in today's automotive component developments.

It contains a high-power full bridge output stage with active current control/limitation specifically designed to drive DC motors, torque motors or solenoid motors found in most automotive actuators (EGR valves, VGTs, turbo waste gates, throttle valves, ...) 

All high-level functions are integrated into and executed by the driver at the reception of predefined commands sent through the CAN bus, making its integration and operation straightforward from the master device's standpoint.​

The embedded software can execute a series of standard ​test schemes (sensor range identification, response-time and hysteresis) with integrated data acquisition/logging and test results processing.  It further includes an advanced position controller, a complex position/PWM profile generator and a test/profile sequencer primarily intended for durability purposes.

Because of it's great versatility, this controller can be used indistinctively in engineering labs for component developments, on durability test benches to generate cycling profiles or on production lines for final quality checks.
