Overview
The ACS108-5SA-AP, produced by STMicroelectronics, is a high-performance AC switch that belongs to the AC switch range built with A.S.D.® technology. This device is capable of controlling a load of up to 0.8 A and features an overvoltage crowbar structure to absorb the inductive turn-off energy. It also includes a gate level shifter driver to separate the digital controller from the main switch, which is triggered by a negative gate current flowing out of the gate pin.
