MAX33011E/12E/14E/15E +5V, 5Mbps CAN Transceiver with 65V Fault Protection, Fault Detection and Reporting, 25V CMR, and 45kV ESD Protection General Description Benefits and Features The MAX33011E/MAX33012E, and MAX33014E/ Integrated Protection Increases Robustness MAX33015E are a family of +5V control area network 65V Fault-Tolerant CANH and CANL (CAN) transceivers with integrated protection for industrial 45kV ESD HBM (Human Body Model) applications. These devices have extended 65V fault 30kV IEC Air-Gap and 12kV IEC Contact protection on the CAN bus for equipment where overvolt- 25V Extended Common-Mode Input Range (CMR) age protection is required.

The system clock then drives the TXD pin and a Fault Detection and Reporting fault code is transmitted through the RXD line back to Detects Overcurrent, Overvoltage, and the controller.

These devices are specified for data rates up to 5Mbps. The transceivers include a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When TXD remains in the dominant state (low) for longer than t , the driver is switched to the reces- DOM sive state, releasing the bus. The MAX33011E/MAX33012E are in a standard 8-pin SOIC package and the MAX33014E/MAX33015E are in a 10-pin TDFN-EP package. This family of devices operates over the -40C to +125C temperature range.
