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.

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
