AS8401中文资料Multipurpose control ASIC for OMNIFET数据手册ams-OSRAM规格书

描述 Description

General Description
The ASIC’ s purpose is to drive one OMNIFET n-channel power FET device. (OMNIFET is a trademark of SGS-THOMSON). The OMNIFET’ s integrated protection circuits (current limitation, over temperature protection, ...) are supplied via the OMNIFET’ s gate input. Thus in the OMNIFET’ s on-state, a DC gate current of 0.5mA is required. In a failure case (e.g. excessive temperature) an internal resistor of about 100W is connected between the OMNIFET’ s gate and source. This state is used to detect errors by the controlling ASIC.Key
