TDE1747

Interface circuit - relay and lamp-driver

Features

■ Open ground protection

■ High output current

■ Adjustable short-circuit protection to ground

■ Thermal protection with hysteresis to avoid the

intermediate output levels

■ Large supply voltage range: + 8V to +45V

■ Short-circuit protection to VCC

Description

The TDE1747 is a monolithic comparator

designed for high current and high voltage

applications, specifically to drive lamps, relays,

stepping motors.

This device is essentially blow-out proof. Current

limiting is available to limit the peak output current

to safe values.

Adjustment only requires one external resistor. In

addition, thermal shut down is provided to keep

the IC from overheating. If internal dissipation

becomes too high, the driver will shut down to

prevent excessive heating. TDE1747 has an open

ground protection. The output is also protected

from shortcircuits 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.
