NXP Semiconductors OM5193
The OM5193H is a combination of a voice coil motor and a spindle motor driver with embedded servo controller designed for use in disk drives. The device operates at 5 and 12 V power supplies and integrates safety functions such as power stages overvoltage protection, power and temperature monitor, over-temperature shutdown and dynamic brake-after-park. The device is contained in a QFP80 package with 18 pins connected to the leadframe thus providing low thermal resistance.| Part No. | OM5193 |
