The TDE/TDF1747 is a monolithic comparator designed for high current and high voltage applications, specifically to drive lamps, relays, stepping motors.
These TDE/TDF1747 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 TDE/TDF1747 will shut down to prevent excessive heating. TDE1747 has an open ground protection.
The TDE/TDF1747 output is also protected from shortcircuits with the positive power supply.
The TDE/TDF1747 device operates over a wide range of supply voltages from standard ± 15 V operational amplifier supplies down to the single + 12 V or + 24 used for industrial electronic systems.
