Introduction

The CA-IS2062 is galvanically-isolated CAN transceivers with a built-in isolated DC-DC converter, that eliminates the need for a separate isolated power supply in space constrained isolated designs. It has the logic input and output buffers separated by a silicon oxide (SiO2) insulation barrier that provides up to 3.75 kVRMS (60s) of galvanic isolation. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. The CA-IS2062 operates from a single 5V supply on the logic side. An integrated DC-DC converter generates the 5V operating voltage for the cable-side. This device does not require any external components other than bypass capacitors to realize an isolated CAN port. The transceivers operate up to 1Mbps data rate and feature integrated protection for robust communication, including current limit, thermal shutdown, and the extended ±58V fault protection on the CAN bus for equipment where overvoltage protection is required. The dominant timeout detection prevents bus lockup caused by controller error or by a fault on the TXD input. These CAN receivers also incorporate an input common-mode range (CMR) of ±30V, exceeding the ISO 11898 specification of -2V to +7V. The CA-IS2062 is available in wide-body 16 pin SOIC(W) package, operates over -40℃ to +125℃ temperature range.
