TDF1747

TDE1747 TDF1747 INTERFACE CIRCUIT – RELAY AND LAMP – DRIVER OPEN GROUND PROTECTION HIGH OUTPUT CURRENT ADJUSTABLE SHORT-CIRCUIT PROTECTION TO GROUND THERMAL PROTECTION WITH HYSTERESIS TO AVOID THE INTERMEDIATE OUTPUT LEVELS LARGE SUPPLY VOLTAGE RANGE : + 10 V TO + 45 V SHORT-CIRCUIT PROTECTION TO VCC DESCRIPTION The TDE/TDF1747 is a monolithic comparator 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 becomes 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.
