The BTS50080-1EGA can be operated in inverse load current condition (+ V
the current flow during inverse mode.
In ON condition a voltage drop across the activated channel of
-V
In OFF condition a voltage drop across the intrinsic body diode of -V
As long as the inverse current does not exceed |-I
and the BTS50080-1EGA will be able to remain in ON mode.
