Abstract:
A semiconductor integrated circuit device for use in a disk drive apparatus, comprising:a first pad to be connected to a motor coil;an output circuit, including an output transistor whose emitter is connected to ground and whose collector is connected to the first pad, for supplying an electric current to the motor coil via the first pad;a second pad for receiving and outputting signals; anda protection diode whose cathode is connected to the second pad and whose anode is connected to ground for protection against surge input,wherein the second pad is disposed a first distance away from the output transistor and the protection diode is disposed a second distance away from the output transistor, wherein the first distance is less than the second distance, thereby reducing a chance of malfunction due to a parasitic transistor occurring in the semiconductor integrated circuit device.
