DESCRIPTION
The TDE/TDF1747 is a monolithic comparator de-
signed for high current and high voltage applica-
tions, specifically to drive lamps, relays, stepping
motors.
These device is essentially blow-out proof. Cur-
rent limiting is available to limit the peak output
current to safe values, the adjustment only re-
quires one external resistor. In addition, thermal
shut down is provided to keep the I.C. from over-
heating. If internals dissipation becomes too
great, the driver will shut down to prevent exces-
sive heating. TDE1747 has an open ground pro-
tection. The output is also protected from short-
circuits with the positive power supply.
The device operates over a wide range of supply
voltages from standard
±
15 V operational ampli-
fier supplies down to the single + 12 V or + 24
used for industrial electronic systems.
