CA-IS3050CW

The CA-IS305xC family of devices is galvanically-isolated controller area network (CAN) transceiver that has superior isolation and CAN performance to meet the needs of the industrial applications. All devices of this family have the logic input and output buffers separated by a silicon oxide (SiO₂) insulation barrier that provides galvanic isolation. Isolation improves communication by breaking ground loops and reduces noise where there are large differences in ground potential between ports. Both the CA-IS3050C and the CA-IS3052C are available in wide-body SOIC8 and SOIC16, but offer different pinout; also, the CA-IS3050C is available DUB8 package. The SOIC16-WB is the industry standard isolated CAN package while the SOIC8-WB and DUB8 are much smaller packages that further reduce the board space in addition to reduced components due to integration of isolation and CAN with protection features. The CA-IS3050CU provides up to 3.75kV_RMS (60s) of galvanic isolation; The CA-IS3050CG/W and CA-IS3052CG/W provide up to 5kV_RMS (60s) of galvanic isolation.

These transceivers operate up to 5Mbps data rate and feature integrated protection for robust communication, including current limit, thermal shutdown, and the extended ±52V 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. All devices operate over -40°C to +125°C temperature range.
