DESCRIPTION Outline Drawing TA8316AS is a dedicated IC integrating IGBT gate drive circuit on a single chip. A high current directly drives IGBT . FEA TURE z Can directly control from a m icrocontroller . z Can directly drive the IGBT gate using a high current. Source current:-200m A (m ax.), sink current 1A (m ax.) z Incorporates a diode to protect the IGBT gate at power on. BLOCK DIAGRAM PIN CONNECTION TIGER ELECTRONIC CO.,LTD
