Pin Description
Pin No.
Pin Name
Function
1
VR1
Reference voltage. The IC's internal reference current is determined by this
voltage and the external resistor Rref.
2
AGC
AGC for the soft switching function. Holds the level used for IC internal
processing fixed even if the B-EMF level fluctuates due to the rotation speed.
3
REF
Reference voltage for the spindle control input, the FCS driver control input,
the TRR driver control input, and the SLD driver control input.
4
VCTL
Spindle control input. Generates forward torque when a voltage higher than
REF is applied, and brake when a voltage lower than REF is applied.
5
BRKSEL
To select the brake (L: Short brake, H: Reverse brake)
6
TRRIN
TRR driver control input. Takes the REF pin voltage as the reference.
7
FCSIN
FCS driver control input. Takes the REF pin voltage as the reference.
8, 9
FCSN & P
FCS driver output
10, 11
TRRN & P
TRR driver output
12
NC
No connection
13
COMPAIN
Amplitude detection comparator input. Connect either the FCS or TRR driver
output to this pin.
14
COMPAVTH
Amplitude detection comparator threshold setting input. (Vin = 0.3 to 1.8 V)
15
COMPAOUT
Amplitude detection comparator output
16
PHASE
Outputs the B-EMF zero cross phase.
17
VFCS
Power supply for the FCS driver, TRR driver, and control block
20
VSLD
Power supply for the slide motor driver and tray motor driver
21
SLDIN
Slide control input. Takes the REF pin voltage as the reference.
22
CE
Chip enable
23
TRYDIR
Tray motor direction control
24
TRYIN
Tray motor drive PWM control input
25
SLDC
Slide off timer time constant. The PWM off time is determined by the external
capacitor and resistor Csld and Rref.
26, 27
SLDP & N
Slide motor driver output
28
SLDS
Slide driver current detection
29, 30
TRYP & N
Tray motor driver output
31
RNF
Spindle driver current detection
32, 33, 34
W, V, U
Spindle driver output
35
PC
Spindle driver output
36
CT
Spindle center tap
37, 39
BC2 & 1
Booster pumping capacitor connection
