+5V, 5Mbps CAN Transceiver with ±65V Fault Protection, Fault Detection and Reporting, ±25V CMR, and ±40kV ESD Protection

Industry's First CAN Transceiver with Fault Detection, Diagnostic Evaluation, and Reporting with ±40kV ESD

Product Details

The MAX33011E–MAX33012E, and MAX33014E–MAX33015E are a family of +5V CAN (Control Area Network) transceivers with integrated protection for industrial applications. These devices have extended ±65V fault protection on the CAN bus for equipment where overvoltage protection is required. The CAN family also incorporates high ±45kV ESD HBM protection and an input common mode range (CMR) of ±25V, exceeding the ISO11898 specification of -2V to +7V, and well suited for applications where ground planes from different systems are shifting relative to each other.

This CAN family incorporates a fault detection feature where it monitors the CANH and CANL line for faults like overcurrent, overvoltage, and transmission failure. When a fault is detected, the FAULT pin goes high, which triggers an external interrupt with the local CAN controller, and the driver and receiver lines are placed in recessive mode. The system clock then drives the TXD pin and a fault code is transmitted through the RXD line back to the controller. When the specific fault code is transmitted and the system is programmed to alert local service personnel, they are able to troubleshoot and debug the problem quicker, providing valuable diagnostics and decreased equipment downtime. In addition, the family features a variety of options to address common CAN application requirements; low-current standby mode, slow slew rate for improved EMI performance, silent-mode to disable the transmitter, low level translation to interface with low voltage controllers, and loopback mode for remote self diagnostics.

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 tDOM, the driver is switched to the recessive state, releasing the bus.

The MAX33011E and MAX33012E are in standard 8-pin SOIC package and the MAX33014E and MAX33015E are in a 10-pin TDFN-EP package. The family of devices operate over the -40°C to +125°C temperature range.
