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.
