The MC73112, MC73112N, MC71112, and MC71112N from PMD are newly released ICs that provide torque control of 3-phase Brushless DC and DC Brush motors with advanced features such as FOC (Field Oriented Control), shunt regulation, PWM (Pulse Width Modulation) signal generation with shoot-through protection, overcurrent & overtemperature protection, braking, and more.
These ICs are the latest additions to PMD’s Juno family of velocity and torque control ICs and are ideal for a wide variety of applications including spindle control, centrifuges, peristaltic pumps, web tensioning, scanner control, industrial fans & pumps, and more. These ICs are available in two package sizes; a 64-pin TQFP measuring 12×12 mm and a 56-pin VQFN package measuring 7 mm x 7mm.
