TDE1798

TDE1798 0.5A INTELLIGENT POWER SWITCH HIGH OUTPUT CURRENT 500mA SHORT-CIRCUIT PROTECTION UP TO VCC = +35V INTERNAL THERMAL PROTECTION WITH EXTERNAL RESET AND SYNCRONIZATION CAPABILITY OPEN GROUND PROTECTION OUTPUT VOLTAGE CAN BE LOWER THAN GROUND FOR FAST INDUCTIVE LOAD DEMAGNETIZATION DIFFERENTIAL INPUTS FOR ANY LOGIC SYSTEM COMPATIBILITY INPUT VOLTAGE CAN BE HIGHER THAN VCC LARGE SUPPLY VOLTAGE RANGE FROM 6V TO 35V SINK AND SOURCE ALARM OUTPUTS NO NEED FOR EXTERNAL CLAMPING DIODE 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 overheating. If internal dissipation becomes too high, PIN CONNECTION (Top view) Minidip ORDERING NUMBER: TDE1798DP the driver will shut down to prevent excessive heating. The output stays null after the overload is off, if the reset input is low. If high, the output will alternatively switch on and off until the overload is removed. Higher current can be obtained by paralleling the outputs of several devices. In this case, the devices can be reactivated simultaneously after an overload if their reset input are connected in parallel. The device operates over a wide range of supply voltages from standard ±15 operational amplifier supplies to the single ±6V or +35...
