PWR-82520/21N
SYNC IN
This input, as shown in FIGURE 9, is used to synchronize the
PWM switching frequency with an external clocking device. The
PWM switching frequency can be pulled to up-to 20% faster than
its free running frequency.
PWM IN
PWM comparator inputs used to control the PWM pulse width.
PWM out or an external triangular waveform is connected to this
pin.
PWM FREQUENCY
The PWM frequency from the PWR-82520N1/N3 (PWR-
82520N10/21N10) PWM OUT pin will free-run at a frequency of
100KHz ± 5KHz (50KHz ± 2.5KHz). The PWM frequency is user
adjustable from 100KHz (50KHZ) down to 10KHz through the
addition of an external capacitor. The PWM triangular waveform
generated internally is brought out to the PWM OUT pin. This
output, or an external triangular waveform generated by the user,
may be connected to PWM IN on the hybrid.
PWM OUT
This is the output of the internally generated PWM triangle wave-
form. It is normally connected to PWM IN. The frequency of this
output may be lowered by connecting an NPO capacitor (CEXT)
between PWM OUT and COMMAND GND. The PWM frequency
is determined by the following formula:
33.0E-6
330pF + CEXTpF
PWR-82520N1/N3:
16.5E-6
330pF + CEXTpF
PWR-82520/21N10:
WARNING: Never apply power to the hybrid without connecting
either PWM OUT or an external triangular waveform to PWM IN!
Failure to do so may result in one or more outputs latching on.

FIGURE 9. SYNC INPUT SIGNAL
PHASE A, B, C
These are the power drive outputs to the motor and switch
between VBUS+ Input and VBUS- Input or become high imped-
ance — see TABLE 3.
ENABLE
The Enable input is an active low (L) logic signal that enables or
disables the internal PWM. In the disable mode (H), the PWM is
shut down and the outputs, Phase A, Phase B and Phase C, are
in an "off" state and no voltage is applied to the motor.
TACH OUT
The TACH OUT provides a tachometer signal that is a square
wave clock with a frequency relative to motor speed that is
derived from the three Hall inputs HA, HB, HC. The tachometer
circuitry combines these three signals into a single pulse train as
a 50%-duty-cycle pulse. There are three pulses that occur every
360 electrical degree. The number of pulses per motor revolu-
tion is formulated below:
DIR OUT
The DIR OUT indicates the direction the motor is rotating, clock-
wise (CW) for a HI (open collector), or counterclockwise (CCW),
indicated as a logic LOW (ground).
CURRENT MONITOR OUT
This is a bipolar analog output voltage representative of motor
current. The CURRENT MONITOR OUT will have the same scal-
ing as the COMMAND IN inputs.
