AS8401 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.

- Automatic mode change between low side and high side use. This allows processing both, relatively low driver voltages (u
- Error detection for the OMNIFET and generation of an error status signal
- Gate to source voltage limitation for the OMNIFET to a maximum of 13V (OMNIFET protection)
- Floating ground interface between the controlling processor (control and status signal) and the driven OMNIFET; provided
- Power reduction in the off-state (Supply current falling to less than 80µA after switching the ASIC off). The driver can
