General Description
TLS2230 General Description
The TLS2230 is a servo-combination predriver designed for use in hard-disk-drive applications. When combined with a power driver such as the TPIC150x, the TLS2230 can drive a voice-coil motor (VCM) and a spindle motor. Figure 1 is a functional block diagram of the servo-combination predriver.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to GND.
