Abstract: PROBLEM TO BE SOLVED: To prevent erroneous position signal detection due to ringing of a terminal voltage generated when energization to a stator winding is changed from OFF to ON with a simpler configuration than a conventional one. SOLUTION: During an off-period of a PWM signal and during a period until the ringing following the turn-on of the PWM is extinguished, on-driving of a transistor 18 is performed, and a reference voltage Vr is generated which has a high voltage level exceeding an allowable voltage range of terminal voltages Vu, Vv, Vw. In other than these periods, off-driving of the transistor 18 is performed, and the reference voltage Vr is used as a virtual neutral point voltage. When the logic of comparison signals Cu, Cv, Cw does not coincide with the next scheduled normal logic accompanying rotation of a motor 2, a control part 20 does not adopt the logic change.

Abstract: PROBLEM TO BE SOLVED: To provide a data transmission apparatus capable of transmitting data with high accuracy.
SOLUTION: In the sensor unit 20A of the data transmission apparatus, a high speed ADC 25 over-samples a sensor signal to convert the sensor signal into a digital signal, which is stored in a data buffer 26, and a communication controller 28 and a communication driver / receiver 29 transmit the digital signal to an in-vehicle LAN 50. On the other hand, the ECU 30 of the data transmission apparatus receives the digital signal via the in-vehicle LAN 50 and stores the digital signal to a data buffer 33, and a delta-sigma converter 35 applies delta-sigma conversion to the digital signal. Since over-sampling by the sensor unit 20A transmits the digital signal with low precision, even when external noise or the like is intruded to the in-vehicle LAN 50, the in-vehicle LAN 50 hardly receives the effect of the noise, and since the delta-sigma conversion by the ECU 30 converts the digital signal with low precision into the digital signal with high precision, the data transmission apparatus can attain data transmission with high precision.

Abstract: PROBLEM TO BE SOLVED: To reduce waveform distortion caused when reduction of a trapezoidal wave load current is started.
SOLUTION: A clamp circuit 23 is provided between a source of a transistor Q11 acting like a high side switch and an output node n2 of an operational amplifier configuring an error amplifier circuit 31. When a drive command signal changes from an H level to an L level, transistors Q18, Q17 are turned on and a voltage Vn2 at a node n2 having increased up to a boosting voltage Vcp is decreased to a Zener voltage Vz of a Zener diode D11 by using a level VL of a load terminal 20 as a reference level. The Zener voltage Vz is a value higher than a threshold voltage Vt of the transistor Q11 and close to the threshold voltage Vt. Thus, gate electric charges of the transistor Q11 are extracted through a transistor Q16 and a load current IL immediately decreases according to a trapezoidal waveform signal Sb.
