Description for the TPIC2050

The TPIC2050 is low-noise-type motor driver IC suitable for 12-V ODD. The 9-channel driver, IC controlled by serial interface, is optimum for driving a spindle motor, sled motor (stepping motor applicable), load motor, focus / tracking / tilt actuators, and stepping motor for the collimator lens.

The spindle motor driver part builds in the sensor-less logic that attains low-noise operation at start-up and while running. Motors or sensors, such as a Hall device, are not required by the starting circuit for self-starting, or for performing position detection by BEMF. As the output stage of all channels works in efficient PWM driving, low-power operation by PWM control is possible. Neutral zone-less control is possible for a focus / tracking / tilt actuator driver. In addition, the spindle part output current limiting circuit, thermal shutdown circuit, sled-end detection circuit, collimator lens end detection circuit, actuator protection, and three beam laser drivers are built in. The newly added built-in thermometer can measure IC temperature.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
