Description for the TPIC2040

TPIC2040 is a very-low noise type motor driver IC suitable for slim or ultra-slim DVD reader/writer. This IC includes integrated current sense resistance that measures SPM current and reduces drive system cost. The 7-channel driver IC controlled by serial I/F is optimum for driving a spindle motor, a sled motor, a load motor, and Focus / Tracking / Tilt actuators. The spindle motor driver uses BEMF detection for sensorless startup and control of the spindle motor

As the output stage of all channels works in efficient PWM driving, it is possible to attain low-power operation by PWM control. Deadband 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, actuator protection and power-reset circuit are built in.

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.
