ISO6762FDWR - 6-Channel Digital Isolator 50Mbps | TI
MPN: ISO6762FDWR ✓ Hoạt độngISO6762FDWR Tóm tắt
Digital isolators are components that provide galvanic isolation between two circuit domains while allowing digital signals to pass across the isolation barrier. They are essential in applications where ground potential differences, noise, or safety requirements demand separation, such as in industrial automation, motor drives, and medical equipment. The ISO6762FDWR uses capacitive isolation technology, which offers high-speed data transfer with low power consumption and excellent EMC performance, as highlighted in the datasheet.
Key features of the ISO6762FDWR include its 50 Mbps data rate, which supports high-speed protocols like SPI and RS-485, and its 1.8V logic support, enabling direct interface with low-voltage microcontrollers. The device also features an enable pin for output control, fail-safe outputs that default to a known state when inputs are unpowered, and a wide temperature range. Its reinforced isolation rating ensures reliable operation in safety-critical applications.
The ISO6762FDWR is built on TI's capacitive isolation technology, which uses high-voltage capacitors to couple signals across the barrier. This architecture provides low propagation delay and high CMTI, making it suitable for applications where fast transients are present. The device also includes integrated noise filtering to enhance signal integrity.
Typical applications include isolating SPI, RS-232, RS-485, and CAN buses in industrial control systems, motor drives, and power converters. Its high data rate and robust isolation make it ideal for communication interfaces in factory automation and building automation.
When designing with the ISO6762FDWR, ensure proper PCB layout with adequate clearance and creepage distances under the isolator to maintain the rated isolation voltage. Also, place decoupling capacitors close to the VCC pins to minimize noise.

Ghi chú thiết kế
Ensure proper PCB layout with adequate clearance and creepage distances under the isolator to maintain the rated isolation voltage. Place decoupling capacitors (0.1µF) close to VCC1 and VCC2 pins to minimize noise.
The ISO6762FDWR operates from 1.8V to 5.5V on both sides. Ensure that the supply voltages are within the specified range and that the power supply is stable. Use separate ground planes for side 1 and side 2 to maintain isolation.
Do not exceed the absolute maximum ratings for supply voltage or isolation voltage. Ensure that the enable pins are properly configured to avoid unintended output states. Verify the channel configuration (4/2) matches your application requirements.
