Pin Description
(cont)
Pin No.
Pin Name
Function
36
PHASE
Outputs the B-EMF zero cross phase. Open corrector. (See the timing chart)
37
BRKSEL
To select the brake mode. Lo: Short brake, Hi: Reverse full brake
(when forward torque input: BRKSEL = H)
38
VREGS
Voltage regulator sense pin (VREGS
≈
3.3 V output)
39
VREGF
Voltage regulator force pin
40
CE
Chip enable. Input Hi: active
41
CT1
Time constant for clock oscillator circuit. The clock oscillator frequency is
determined by the external capacitor and resistor Ct1 and Rt.
42
CT3
Time constant for PWM carrier oscillator. The carrier frequency is determined
by the external capacitor and resistor Ct3 and Rt.
43
VSS
Control block power supply. 5 V
44
CT2
Time constant for start-up oscillator. The start-up oscillator frequency is
determined by the external capacitor and resistor Ct2 and Rt.
45
RT
Reference voltage (3.3 V). The IC’s internal reference current is determined by
this voltage and the external resistor Rt.
46
SLDLIM
SLD output maximum duty setting
47
SLDIN
SLD control input pin
48
TRYF
TRY driver forward input
49
TRYR
TRY driver reverse input
50
TRYLIM
TRY output voltage setting pin
51
NC
No connection
52
