The E910.72 allows independent positioning of up to 5 DC motors. Pulse detection circuits convert the commutation current of the motors into countable digital signals especially for positioning of HVAC flap actuators.
Via an SPI a μC sends motor address, direction, and pulse count command to the device. The corresponding motor will then be driven to the desired position, and the actual number of counts is sent back to the μC.
Diagnostic data such as overcurrent, overtemperature and motor stall is also transmitted via the SPI. An open drain low side output indicates when a required motor position is reached or diagnostic data is available. ICs can be connected in a daisy chain.
- Operating supply voltage range 6V to 19V
