Electrical Characteristics (Continued)
Unless otherwise noted, V DD =12V and T J =-40°C to +125°C. Currents are defined as positive into the device (I sink ) and
negative out of the device (I source ).

Notes:
8. The internal gate-drive regulators provide optimum gate-drive voltage when operating from a rail of 8V to 27V.
The FAN3278 can be driven from a voltage rail of less than 8V; however, with reduced gate drive current.
9. EN inputs have near-TTL thresholds (refer to the ENABLE section) .
10. Not tested in production.
11. See the Timing Diagrams of Figure 5 and Figure 6 .
