TDE1747 Datasheet | STMicroelectronics

DESCRIPTION The TDE/TDF1747 is a monolithic parator designed for high current and high voltage applications, specifically to drive lamps, relays, stepping motors. These device is essentially blow-out proof. Current limiting is available to limit the peak output current to safe values, the adjustment only requires one external resistor. In addition, thermal shut down is provided to keep the I.C. from overheating. If internals dissipation bees too great, 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.
