AC POWER CONTROLLERS
DESCRIPTION:
The LS7310-LS7313 are MOS integrated circuits specifically
designed for motor speed control applications in appliances
such as blenders, etc. I/Os (PLs) are provided for selecting/
indicating from one to ten power levels. The LS7310 and 7311
are designed for pushbutton control. The LS7312 and LS7313
are designed for touch control. (See Fig.4A and 4B)
INPUT/OUTPUT DESCRIPTION:
PL1-PL10 (Pins 1-9, 18)
Ten inputs/outputs for selecting ten output phase angles (pow-
er levels). When no power level is selected (such as after sys-
tem power-up), PL1-PL10 all act as inputs. When a power level
is selected by applying a logic zero at one of these inputs for
T
H
time (See Dynamic Characteristics), the selected input
switches status to become an output in order to drive a display,
such as an LED. It switches back to the input state only when
another PL input is activated. (See Note 1)
RUN (Pin 13)
When a logic 0 is applied to the RUN input for T
H
time, the out-
put (TRIG) is turned on at a phase angle selected earlier by
one of the PL I/Os. If no power level was selected prior to the
application of the RUN input, the circuit remains unaffected.
Note that once the TRIG output has been enabled, its phase
angle can be altered by applying any other PL input without the
need to apply the RUN input again. (See Note 1)
OFF (Pin 11)
When a logic 0 is applied to this input for T
H
time, TRIG output
is turned off, if it was on. If TRIG was already off, the circuit re-
mains unaffected. Note that OFF input does not alter the power
level selected by a PL input. Following an OFF operation,
TRIG can be turned on at the previous phase angle by applying
the RUN input. (See Note 1)

APPLICATIONS:
Universal and shaded-pole motor speed control for modern
appliance designs. Eliminates awkward mechanical switch
assemblies and multi-tapped motor windings.
PULSE (Pin 12)
A logic 0 applied to this input turns the TRIG output on for
as long as the PULSE input is maintained. The PULSE input
however, has no effect if no power level is in selection or if
the TRIG output has already been turned on by means of
the RUN input. (See Note 1)
SYNC (Pin 15)
Input for PLL reference frequency (50Hz/60Hz). All internal
clock frequencies are synchronized with the SYNC input.
CAP (Pin 14)
Input for component connection for the PLL filter capacitor.
TRIG (Pin 17)
This output is designed to drive a triac in series with the
load and control its firing angle with respect to the AC line.
The LS7310 and LS7312 provide a nominal 33μs output
pulse width. Since some motors have large inductive loads
producing a large phase delay between voltage and current,
a wider output pulse may be required. The LS7311 and
LS7313 produce a 1ms output pulse width. Otherwise,
these parts are identical to the LS7310 and LS7312,
respectively.
Vss (Pin 16)
Supply voltage positive terminal.
V
DD
(Pin 10)
Supply voltage negative terminal (ground).
NOTE 1
: LS7310, LS7311 have an internal pullup resistor on this
input and LS7312, LS7313 do not. (See DC Electrical Character-
istics.)
