Description

This PHN70308 product is used to drive high performance, three phase brushless d.c. motors in computer disk drives.

The PHN70308 contains seven, n-channel enhancement mode trenchMOS transistors in a surface mounting plastic package. Six of the transistors can be configured as a three phase bridge to drive the spindle of a disk drive motor. The remaining transistor delivers power to the three phase bridge during normal operation. In the event of a power failure occurring whilst the motor is still spinning, this transistor isolates the computer power supply from the back emf generated by the motor.

The PHN70308 is supplied in the surface mounting SOT341-1 (SSOP28) package.
