DESCRIPTION
The ACS302 belongs to the AC line switch family
built around the ASD鈩?concept. This high
performance device inludes 3 bidirectionnal AC
switches able to control an 0.2A resistive or
inductive load device.
Each ACS鈩?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.
ASD and ACS are trademarks of STMicroelectronics.
