The current source characteristic of this device is
adapted to the on-linear current gain behaviour of
the power transistor providing a minimum power
dissipation. The TDA8140 is internally protected
against short circuit and thermal overload.

3. Whe n the remote input goes from HIGH to LOW the BU508 is switched off and it remains in this condition for the time t

4. The sense in put volt age VS is internally limited and results in a limited positive out put current Ip0 = g VS limit. Note that due to
the storage time tS of the BU508 limiting of VS leads to a reduced base current of the BU508 and the output current I0 is going to
the positive quiescent current IO0.
