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 adjustmentonly 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.

ORDER CODES

The output is also protected against short-circuits

with the positive power supply.

Package

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.
