1 / 16 page  March 2007 Rev 2 1/16 16 TDE1767 TDE1787 Interface circuit (relay and Lamp-driver) Features ■ Open ground protection ■ High output current ■ Adjustable short-circuit protection ■ Internal thermal protection with external reset ■ Large supply voltage range ■ Alarm output ■ Input voltage can be higher than VCC ■ Output voltage can be lower than ground (VCC - VO ≤ VCC[max]) Description The TDE1767, TDE1767A, TDE1787, TDE1787A are a monolithic amplifiers designed for high current and high voltage applications, specifically to drive lamps, relays, stepping motors. The devices are assentially blow-out proof. The output is prois protected from short-circuits with the positive supply or drive. In addition thermal shut down is provited to keep the IC from overheathing. If internal dissipation becomes too high, the driver will shut down to prevent excessive heating. The output stays null after the overheating is off, if the reset input is low. If high the output will alternatively switch-on and off until the overload is removed. The devices operates over a wide range voltages from standard 15V operational amplifier supplies to the single +6V or +48V used for industrial electric systems. Input voltages can be higher than in the VCC. An alarm output suitable for driving a LED is provited. This LED, normally on (if referred to ground), will die out or flash during an overload depending on the state of the reset input. The output is low in open ground conditions.
