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.

DIP-8

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.
