Sample Application Circuit (Optical Disk Spindle Motor)
Usage Notes
1. Position detector circuit (Hall element input circuit)
The position detection circuit consists of a differential amplifier, and will operate if a differential input of 40 mVp-p
(minimum) is provided. However, an input of 100 mVp-p is desirable from the standpoint of noise and other
problems.
The input DC level must be within the common mode input voltage range (1.5 to (VCC – 1.8) V).
2. Current limiter circuit
The output current limiter operates by holding the sink side output transistor in an unsaturated state.
The current limit value can be calculated from the following formula.
I = VCS/Rf
Where: VCS = 0.58 V typical, Rf = The value of the resistor between pin 11 and ground.
3. FG input
The following three methods can be used to input the speed signal FG from the motor.
The signal can be input to FGIN through an amplifier. (FG mode)
The Hall input IN1 can be used as the FG input. (single Hall FG mode)
This is set up by connecting FGIN to VREG.
The composite signal from the IN1, IN2 and IN3 Hall inputs can be used as the FG input. (triple Hall FG mode)
This is set up by connecting FGIN to ground.
