Description

The TDE1767, A/TDE1787, A are a monolithic amplifiers designed for high current and high voltage applications, specifically to drive lamps, relays, stepping motors.

The devices TDE1767, A/TDE1787, A are assentially blow-out proof. The output is prois protected from short-circuitswith 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 outputwill alternatively switch-on and off until the overload is removed.

The devices TDE1767, A/TDE1787, A operates over a wide range voltages from standard 15 V 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.
