DESCRIPTION
The TDE1767, A/TDE1787, A are a monolithic am-
plifiers 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 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.
