TDE3247

Interface circuit (relay and lamp driver)

Features

■ High output current

■ Adjustable short-circuit protection to ground

■ Internal thermal protection with hysteresis to

avoid the intermediate output levels

■ Large supply voltage range: 8 to 30V

■ Short-circuit protection to VCC

■ Open ground protection

Description

The TDE3247 is a monolithic amplifier designed

for high current and high voltage applications,

specifically to drive lamps, relays and stepping

motors.

The Device is essentialy blow-out proof. Current

limiting is available to limit the peak output current

to a safe value, the adjustment only required an

external resistor.

In addition, thermal shut-down is provided to keep

the IC from overheating.

If external dissipation becomes too high, the

driver will shut-down to prevent excessive

heating.

The output is also protected against short-circuit

with the positive power supply.

The device operates over a wide range of supply

voltage from standard ±15V operational amplifier

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

industrial electronic systems.
