... IC operation. (5) Motor constraint protection circuit The LB11610P includes a built-in motor constraint protection circuit to protect the IC itself and the motor if the motor is physically constrained from moving. If the Hall sensor input signals do not switch states for a period in excess of a certain fixed time with the motor in the driven state, the outputs are turned off. This time is set by the discharge time of the capacitor and resistor connected to the CSD pin ...
