1 / 11 page TDE1747 TDF1747 INTERFACE CIRCUIT – RELAY AND LAMP – DRIVER OPEN GROUND PROTECTION HIGH OUTPUT CURRENT ADJUSTABLE SHORT-CIRCUIT PROTEC- TION TO GROUND THERMAL PROTECTION WITH HYSTERE- SIS TO AVOID THE INTERMEDIATE OUT- PUT LEVELS LARGE SUPPLY VOLTAGE RANGE : + 10 V TO + 45 V SHORT-CIRCUIT PROTECTION TO VCC DESCRIPTION The TDE/TDF1747 is a monolithic comparator de- signed for high current and high voltage applica- tions, specifically to drive lamps, relays, stepping motors. These device is essentially blow-out proof. Cur- rent limiting is available to limit the peak output current to safe values, the adjustment only re- quires one external resistor. In addition, thermal shut down is provided to keep the I.C. from over- heating. If internals dissipation becomes too great, the driver will shut down to prevent exces- sive heating. TDE1747 has an open ground pro- tection. The output is also protected from short- circuits with the positive power supply. The device operates over a wide range of supply voltages from standard ± 15 V operational ampli- fier supplies down to the single + 12 V or + 24 used for industrial electronic systems. This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
