I²PAK ACST610-8R Functional diagram OUT Description The ACST6 series belongs to the ACS™/ACST power switch family built with A.S.D.® (application specific discrete) technology. This high performance device is suited to home appliances or industrial systems, and drives loads up to 6 A. This ACST6 switch embeds a Triac structure and a high voltage clamping device able to absorb the inductive turn-off energy and withstand line transients such as those described in the IEC 61000-4-5 standards. The ACST610 needs only low gate current to be activated (IGT < 10 mA) and still shows a high noise immunity complying with IEC standards such as IEC 61000-4-4 (fast transient burst test).

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 Figure 16 and Figure 17. Figure 16.

Universal drum motor control – typical diagram Universal motor Stator Rotor 12V AC Mains Motor direction setting MCU Speed motor regulation ACST Rg 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 VCL. The ACST6 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 Figure 18 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 Figure 19. 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.
