This high performance switch circuit is able to control a load up to 1 A. The ACS™ 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. S ON D COM G 1/10 April 2003 - Ed: 2A ACS110-7SN/SB2 ABSOLUTE RATINGS (limiting values) For e...
