ACS110-7SN/SB2 ASD AC LINE SWITCH AC Switch Family MAIN APPLICATIONS n AC static switching in appliance control systems COM n Drive of low power high inductive or resistive loads like OUT - relay, valve, solenoid, dispenser COM - pump, fan, micro-motor G - defrost heater SOT-223 FEATURES ACS110-7SN n Blocking voltage : V /V = +/-700V DRM RRM n Avalanche controlled : V typ = 1100 V CL G n Nominal conducting current : I =1A T(RMS) n Gate triggering current : I <10mA GT n Switch integrated driver OUT n High noise immunity : static dV/dt >500V/s COM COM COM BENEFITS COM n No external protection snubber or varistor DIL-8 needed ACS110-7SB2 n Enables equipment to meet IEC 61000-4-5 & IEC 335-1 (DIL-8 package) n Reduces component count up to 80 % n Interfaces directly with the microcontroller n Eliminates any gate kick back on the microcontroller FUNCTIONAL DIAGRAM n Allows straightforward connection of several ACS on same cooling pad (SOT-223) OUT DESCRIPTION The ACS110 belongs to the AC line switch family built around the ASD concept. This high perfor- mance switch circuit is able to control a load up to 1 A. S The ACS switch embeds a high voltage clamp- ing structure to absorb the inductive turn off energy ON and a gate level shifter driver to separate the digital controller from the main switch. It is triggered with a negative gate current flowing out of the gate pin.
