... S sth2 (*) According to the intervention of the current limiting block. (**) A cold lamp filament capacitive load may activate the current limiting circuit of the I PS, when the IPS is initially turned on. TDE1891 uses Diag2 to signal such condition, TDE1890 does not. 4/12 Test Condition @ Ifsd = 2. 10ms 20 2.5A di/dt = 25A 24V ...

... Alternative circuit solutions can be implemented to divert the demagnetization stress from the TDE1890/ exceeds 1J. In all cases it is rec- ommended that at least 10V are available to de- magnetize the load in the turn-off phase. A clamping circuit connected between ground and the output pin is not recommended ...
