Application information ACST6 2 Application information 2.1 Typical application description The ACST6 device has been designed to control medium power load, such as AC motors in home appliances. Thanks to its thermal and turn off commutation performances, the ACST6 switch is able to drive an inductive load up to 6 A with no turn off additional snubber. It also provides high thermal performances in static and transient modes such as the compressor inrush current or high torque operating conditions of an AC motor. Thanks to its low gate triggering current level, the ACST6 can be driven directly by an MCU through a simple gate resistor as shown Figure16 and Figure17. Figure 16. Compressor control – typical diagram Compressor Compressor AC Mains PTC AC Mains Electronic PTC ACST starter 2 1 logical circuitry ACST Start 3 switch ACST Run switch Electronic ACST thermostat Rg Rg Rg Gate Gate Power supply Driver Power supply Driver Compressor with integrated e-starter Compressor with external electronic drive 6/20 DocID7297 Rev 11

Universal drum motor control – typical diagram Universal motor Stator Rotor 12V AC Mains Motor direction setting MCU Speed motor ACST Rg regulation Vcc MCU 2.2 AC line transient voltage ruggedness In comparison with standard Triacs, which are not robust against surge voltage, the ACST6 is self-protected against over-voltage, specified by the new parameter V . The ACST6 CL switch can safely withstand AC line transient voltages either by clamping the low energy spikes, such as inductive spikes at switch off, or by switching to the on state (for less than 10 ms) to dissipate higher energy shocks through the load. This safety feature works even with high turn-on current ramp up. The test circuit of Figure18 represents the ACST6 application, and is used to stress the ACST switch according to the IEC 61000-4-5 standard conditions. With the additional effect of the load which is limiting the current, the ACST switch withstands the voltage spikes up to 2 kV on top of the peak line voltage. The protection is based on an overvoltage crowbar technology. The ACST6 folds back safely to the on state as shown in Figure19. The ACST6 recovers its blocking voltage capability after the surge and the next zero current crossing. Such a non repetitive test can be done at least 10 times on each AC line voltage polarity.
