Ecumaster Dual H-Bridge module

In modern vehicles, many actuators and pumps are driven by DC electric motors that require relatively high currents along with precise control of duty cycle and direction. Examples include variable valve lift mechanisms, multiple ITBs using a single control unit, and electric 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's ITB electronic throttle valves (which require a fairly high current) when the module acts as a bridge between an additional control unit and the throttle valve. Another common installation is in a door, where one H-bridge can operate the electric windows and a second lock function. This device can also be used as a general-purpose high-current output expander (four 10A high/low side outputs) for engine management systems. The CNC-machined aluminum casing facilitates excellent heat dissipation and environmental protection, which is a key factor in product reliability.
