DESCRIPTION

The TDE1737-TDF1737 is a monolithic amplifier

designed for high current and high voltage applica-

tions, specifically to drive lamps, relays and control

of stepper motors.

This device is essentially blow-out proof. Current

limiting is available to limit the peak output current

to a safe value, the adjustment only requires one ex-

ternal resistor. In addition, thermal shut down is pro-

vided to keep the I.C. from overheating. If internal

dissipation becomes too great, the driver will shut

down to prevent excessive heating.

The output is also protected against short-circuits

with the positive power supply.

The device operates over a wide range of supply

voltages from standard ± 15 V operational amplifier

supplies down to the single + 12 V or + 24 used for

industrial electronic systems.
