TDE1737
Interface circuit - relay and lamp-driver
Features
■ High output current
■ Adjustable short-circuit protection
■ Thermal protection with hysteresis to avoid the
intermediate output levels
■ Large supply voltage range: + 8V to +45V
Description
The TDE1737 is a monolithic amplifier designed
for high current and high voltage applications,
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 external resistor. In addition, thermal
shut down is provided 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
.
