DESCRIPTION

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

The devices are assentially blow-out proof. The
output isprois protectedfromshort-circuits withthe
positive supply or drive. In addition thermal shut
down is provitedto keepthe IC from overheathing.
If internal dissipationbecomes 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 highthe outputwillalternatively
switch-onand off until the overloadis removed.

The devices operates over a wide range voltages
from standard 15 V operational amplifier supplies
to thesingle+6Vor+48Vusedforindustrialelectric
systems. Input voltages can be higher than in the

.

V

CC

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 groundconditions.
