Robust 4Mbps CAN FD µModule Isolator with Power Improves System Reliability
2016-09-13 | ReturnThe LTM2889 features an integrated, low EMI, DC/DC converter that powers the isolated transceiver and provides up to 0.75W of isolated power for CAN node components. In addition to the many built-in protection mechanisms, the device features an extended ±36V common mode range to enable operation in electrically noisy environments and in the presence of ground loops. The LTM2889 operates at data rates between 22kbps and 4Mbps, with an adjustable slew rate to reduce EMI at lower data rates. A shutdown mode brings all of the LTM2889’s outputs to high impedance and reduces power consumption to less than 1µA.
The LTM2889 is offered in commercial, industrial and automotive temperature grades and is available in a low profile 15mm x 11.25mm x 3.42mm surface mount BGA package. All integrated circuits and passive components are housed in this Linear Technology, RoHScompliant μModule package. Pricing starts at $9.96 each in 1,000 piece quantities. The LTM2889 joins a family of μModule isolators that includes isolated RS485, RS232, USB, SPI, I²C and GPIO. Please visit www.linear.com/isolator for more product selection and information.
