Ecumaster Dual H-Bridge Module

In modern automobiles, there are numerous actuators and pumps driven by DC electric motors that require relatively high current, along with precise duty cycle and direction control. Examples include variable valve lift mechanisms, multiple individual throttle body (ITB) systems utilizing a single 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 either directly or via CAN messages. This solution is ideal for BMW individual throttle body (ITB) systems (which require quite high current), as 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 drive power windows and the central locking function. This device can also be used as a general-purpose high-current output expander (4 x 10A high-side/low-side outputs) for engine management systems. The CNC-machined aluminum enclosure facilitates optimal heat dissipation and environmental protection, a key factor for product reliability. Key features
