In modern cars, there are many actuators and pumps driven by DC electric motors which require relatively high current along with precise duty cycle control and direction. A few examples are variable valve lift mechanisms, multiple ITBs using one control unit and power windows.
Sometimes the best option is to use remotely installed high current H-Bridges. Our new module consists of two 10A H-Bridges controlled directly or via CAN messages.
This solution is perfect for BMW ITB electronic throttles (quite a high currentrequired) when the module acts as a bridge between an aftermarket ECU and the throttle.Another common installation is in a door, where one H-Bridge can operate powerwindowsand second lock functionality.
This device can also be used as a high current general purpose output expander (4 x 10Ahigh side / low side outputs) for engine management systems.
CNC machined aluminium enclosure facilitates perfect heat dissipation and environmental protection which is a key factor of product reliability.
