DESCRIPTION

The TDE3237 is a monolithic amplifier designed

for high-current and high-voltage applications,

specIally to drive lamps, relays and stepping mo-

tors.

The 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

external resistor. In addition, thermal shut down is

provided to keep the IC from overheating. If exter-

nal dissipation becomes too great, the driver will

shut down to prevent excessive heating.

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

±15V operational amplifier

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

industrial electronic systems.
