TDE1747：Interface circuit - relay and lamp-driver
The TDE1747 is a monolithic comparator designed for high current and high voltage applications, specifically to drive lamps, relays, stepping motors.
This device is essentially blow-out proof. Current limiting is available to limit the peak output current to safe values.
Adjustment only requires one external resistor. In addition, thermal shut down is provided to keep the IC from overheating. If internal dissipation becomes too high, 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. The device operates over a wide range of supply voltages from standard ± 15V operational amplifier supplies down to the single +12V or +24V used for industrial electronic systems.
Key Features
- Short-circuit protection to VCC
- Open ground protection
- Adjustable short-circuit protection to ground
- High output current
- Large supply voltage range: + 8V to +45V
- Thermal protection with hysteresis to avoid the intermediate output levels
