Ecumaster Dual H-Bridge


The device contains two independent H-Bridges, with over-current and short circuit protection, capable of 10A continuous current and 30A peak current. H-Bridges can be controlled via device inputs or CAN bus messages.

Voltage range: 6V - 28V (12V and 24V automotive installations)

Output current: 10A continuous, 30A peak

4 analogue (0-5V) / digital (35Hz - 200Hz PWM) inputs

Output PWM: 12bit 3.9kHz

Device can be used to supply protected low side (GND) or high side (VBat) supply independently to each of 4 outputs for bidirectional DC motor control. Low side output can be PWM modulated on per bridge basis. Common use cases can be:

  • Electric windows controller
  • High current electronic throttle body amplifier
