TI's TIDA-01357 reference design offers a DC motor control solution for multiple automotive HVAC flap actuators or dampers. This design demonstrates a cost-effective motor driver solution for six flap actuators/dampers where all six motors can be driven simultaneously with an output current up to 0.4A per motor.
This reference design maintains a small solution size and low quiescent current in addition to offering reverse battery and load dump protection.
Direct battery operation (12V system); survives voltages up to 45V
Withstands reverse battery conditions and load dump conditions (12V system)
Three-chip solution to drive up to six motors
Compact layout; does not require external FETs
Overcurrent, undervoltage and overtemperature protection with diagnostics feature
