application information acst12 6/13 doc id 15238 rev 3 2 application information 2.1 typical application description the acst12 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 acst12 switch is able to drive an inductive load up to 12 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 acst1210-7 can be driven directly by a mcu through a simple gate resistor as shown in figure 16 . figure 16. compressor control ? typical diagrams compressor electronic starter electronic thermostat acst rg acst power supply ac mains gate driver logical circuitry 1 2 3 ptc compressor with integrated e-starter compressor start switch run switch ptc rg acst power supply gate driver acst rg ac mains compressor with external electronic drive
acst12 application information doc id 15238 rev 3 7/13 figure 17. universal drum motor control ? typical diagram 2.2 ac line transient voltage ruggedness in comparison with standard triacs, which are not robust against surge voltage, the acst12 is self-protected against over-voltage, specified by the new parameter v cl . the acst12 switch can safely withs tand ac line transient voltages either by clamping the low energy spikes, such as the 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 acst12 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 th e 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 acst12 folds back safely to the on state as shown in figure 19 . the acst12 recovers its blocking voltage capabilit y after the surge and th e next zero crossing current. such a non repetitive test can be done at least 10 times on each ac line voltage polarity. universal motor motor direction setting speed motor regulation rg ac mains stator mcu vcc 12v acst rotor mcu
