DESCRIPTION The ACS302 belongs to the AC line switch family built around the ASDTM concept. This high performance device inludes 3 bidirectionnal AC switches able to control an 0.2A resistive or inductive load device. Each ACSTM switch embeds a high voltage clamping structure to absorb the inductive turn off energy 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.
