| 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 SO-14 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.
