ISL8487EIPZ

ISL8487EIPZ Application Field and Working Principle

ISL8487EIPZ belongs to the category of interface - drivers, receivers and transceivers. It is a protected high-speed CAN transceiver that supports CAN FD and enhanced CAN features including faster data rate, improved message filtering and selective wake-up. This device is available in both industrial and automotive temperature grades, providing a cost-effective solution for industrial, automotive and other robust CAN applications. It provides two independent CAN communication interfaces: one is CAN controller\'s CANL and CANH interface, and the other is CAN transceiver\'s CANL and CANH interface. The protection features of the device provide system level immunity to transients. The isolation features also protect the device against electrical failure of these interfaces.

Working Principle

The ISL8487EIPZ works on the principle of providing a highly reliable and protected high-speed CAN transceiver with an integrated bit rate up to 8Mbps, and two independent CAN communication interfaces. These interfaces consist of both a CAN controller\'s CANL and CANH interface, and a separate CAN transceiver\'s CANL and CANH interface. The device is designed to provide system-wide protection against transients and is equipped with a built-in failsafe latch circuit, which ensures that any connection break or driver failure will cause a stored logic low state on CANH and CANL. The device houses a built-in CAN controller and transceiver that allows for enhanced protection for CAN bus operation without a separate transceiver or controller. The device includes built-in higher data rate feature that allows up to 8 Mbps for CAN bus communications.

The device includes a 3.3V or 5V DC-DC converter which is used to provide supply voltage for the CAN transceiver and requires a power supply to operate the device. It is compatible with both single-ended and differential voltage inputs, and also features a wide operating temperature range of -40°C~125°C. In addition, the device features an on-chip ESD protection circuit, which provides immunity up to 6kV. This device is compliant with the ISO 11898-2 specification, which states the device\'s transiency (noise) protection must be greater than 4kV.

The CAN transceiver also features an integrated low-pass filter to help suppress high frequency interference, and an integrated common mode choke that helps reduce EMI. In addition, the device is designed with a data rate that is too fast for standard CAN bus applications. This device provides reliable and safe communication between a host and a transceiver, and helps protect against transience and noise induced failures in the CAN communication system.

Conclusion

The ISL8487EIPZ is a protected high-speed CAN transceiver and falls under the category of interface - drivers, receivers and transceivers. This device is capable of reliably and safely communicating between a host and a transceiver, and provides protection against transience and noise induced failures in the CAN communication system. It also features an integrated bit rate up to 8 Mbps, and two independent CAN interfaces. The device is also designed with many protection features and is equipped with a failsafe latch circuit that ensures that any connection break or driver failure will cause a stored logic low state on CANH and CANL.
