| LSI/CSI UL (R) LS7314-7315 (631) 271-0400 FAX (631) 271-0405 LSI Computer Systems, Inc. 1235 Walt Whitman Road, Melville, NY 11747 A3800 AC POWER CONTROLLERS FEATURES: * 10 I/Os to Select/Indicate up to ten Power Levels * Inputs activated by Touch or Pushbutton Switch * Output switches pure and precise AC Power to Load * Operates with 50Hz/60Hz line frequency * Rugged, latchup-free process technology * +10V to +14V operation (Vss-VDD) * LS7314, LS7315 (DIP; LS7314-S, LS7315-S (SOIC) - See Figure 1 APPLICATIONS: * Universal and shaded-pole motor speed control for modern appliance designs. Eliminates awkward mechanical switch assemblies and multi-tapped motor windings. (See Fig. 4C) * Multi-level light switches. (See Fig. 4D) DESCRIPTION: The LS7314 - LS7315 are MOS integrated circuits specifically designed for appliance motor speed control, lighting control, etc. I/Os (PLs) are provided for selecting/indicating from one to ten power levels. The LS7315 is designed for pushbutton control. The LS7314 is designed for touch control. (See Figures 4A and 4B) INPUT/OUTPUT DESCRIPTION: PL1-PL10 (Pins 1-8, 15, 16) Ten inputs/outputs for selecting ten output phase angles (power levels). When no power level is selected (such as after system 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 TH time (See Dynamic Characteristics), the output (TRIG) is turned on at the phase angle selected and the PL input switches status to become an output in order to drive a display, such as an LED. It switches back to the input state when another PL input is activated or when OFF is selected. (See Note 1) OFF (Pin 10) If TRIG is on, a logic 0 applied to the OFF input for TH time turns TRIG output off and switches the selected PL back to the input state. If TRIG is off, activating OFF leaves the circuit unaffected. Following an OFF activation, TRIG can be turned on by applying any PL input. (See Note 1) SYNC (Pin 12) Input for PLL reference frequency (50Hz/60Hz). All internal clock frequencies are synchronized with the SYNC input. CAP (Pin 11) Input for component connection for the PLL filter capacitor. 7314-040197-1 A CONNECTION DIAGRAM - TOP VIEW PL3 PL4 PL5 PL6 PL7 PL8 PL9 1 2 3 4 5 6 7 16 15 14 13 12 11 10 9 FIGURE 1 LS7314 LSI PL2 PL1 Vss (+V) TRIG SYNC CAP OFF V DD (-V) PL10 8 TRIG (Pin 13) This output is designed to drive a triac in series with the load and control its firing angle with respect to the AC line. A 1ms output pulse width is provided to enable the triac to fire even with inductive loads which cause significant phase delays between voltage and current. Vss (Pin 14) Supply voltage positive terminal. VDD (Pin 9) Supply voltage negative terminal (ground). NOTE 1: LS7315 has an internal pullup resistor on this input and LS7314 does not.
