... ODE FOR DEMAGNETIZATION ENERGY UP TO 150mJ SEVERAL DEVICES CAN BE CONNECTED IN PARALLEL DESCRIPTION The TDE1798 is an interface circuit delivering high currents and capable of driving any type of loads. The output is protected from short-circuits with the positive supply or ground. In addition thermal shut down is provided to keep the IC from over- heating ...

... BRVEO Notes: 2) For operating at high temperature, the TDE1798 must be derated based on a 150 C maximum junction temperature and the junction-ambient thermal resistance. 3) The offset voltage given is the maximum value of input differential voltage required to drive the output voltage within 2V of the ground or the supply voltage ...
