The TDE1747 is a monolithic comparator designed for high current and high voltage applications, specifically to drive lamps, relays, and stepping motors. It features open ground protection, high output current, adjustable short-circuit protection to ground, thermal protection with hysteresis to avoid intermediate output levels, and a large supply voltage range.
The TDE1747 is a monolithic comparator designed for high current and high voltage applications, specifically to drive lamps, relays, and stepping motors. It is essentially blow-out proof and features current limiting to limit peak output current to safe values with adjustment requiring only one external resistor. The device includes thermal shut down to prevent overheating and operates over a wide supply voltage range from +8V to +45V.
