TDE1747FPT

TDE1747FPT Description

The TDE1747FPT from STMicroelectronics is a high-performance bipolar high-side power driver designed for relay and solenoid driver applications. This surface-mount IC operates with a 1:1 input-to-output ratio, delivering up to 1A output current across a 10V to 45V load voltage range. Unlike traditional drivers requiring external supply voltages, the TDE1747FPT operates without a Vcc/Vdd supply, simplifying system design. Its current-limiting (adjustable) and over-temperature fault protection ensures robust operation in demanding environments. Packaged in a 14SO tape & reel (TR), it meets ROHS3 and REACH compliance, making it suitable for modern eco-conscious designs.

TDE1747FPT Features

• Bipolar High-Side Driver: Optimized for relay/solenoid control with 1A max output.
• Wide Load Voltage Range (10V–45V): Supports diverse industrial and automotive applications.
• No Supply Voltage Required: Eliminates need for auxiliary power, reducing BOM complexity.
• Integrated Protection: Adjustable current limiting and thermal shutdown enhance reliability.
• Robust Packaging: 14SO (Tape & Reel) with MSL3 (168-hour) moisture resistance.
• Compliance: ROHS3, REACH, ECCN EAR99, ensuring global regulatory adherence.

TDE1747FPT Applications

• Industrial Automation: Solenoid valve drivers in pneumatic/hydraulic systems.
• Automotive Systems: High-side switching for relays in ECU and power distribution modules.
• Home Appliances: Motor and actuator control in washing machines/refrigerators.
• Power Management: Load drivers in 48V mild-hybrid vehicles or DC-DC converters.

Conclusion of TDE1747FPT
