Relay and Lamp Driver 14-Pin SOIC T/R

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.
