Automotive CAN Transceiver offers advanced power management.
May 15, 2008 -
MAX13041 provides ±80 V fault-protected voltage range as well as ±12 kV ESD protection on CAN bus lines. Diagnostics and over-temperature protection are included as well as 7 internal flags to indicate various fault conditions. Unit features 5 modes of operation, including sleep mode, which reduces current consumption to 18 µA in clamp-30, always-on nodes. Conformant to ISO 11898-2 specification, it is available in RoHS-compliant, 14-pin SO package and operates from -40 to +125°C.

Industry's Most Robust, ±80V Fault-Protected, High-Speed CAN Transceiver Provides Advanced Power Management
±80V fault-protected, high-speed controller area network transceiver
o The MAX13041 is a ±80V fault-protected, high-speed, automotive CAN transceiver conformant to the ISO 11898-2 specification.
o This device provides the industry's most robust protection, as well as advanced power management, thus reducing the standby current of ECUs in automotive applications that require a CAN interface.
o To minimize current consumption, this device reduces the current consumption of an entire clamp-30 node to 18µA (typ) in sleep mode. It then employs wake-on-CAN functionality to restore power to the node upon detection of CAN bus activity.
o The combination of a wide, CAN-bus input-voltage range (±80V), high ESD protection (±12kV), and low power consumption (18µA, typ) makes the MAX13041 ideal for automotive applications.
SUNNYVALE, CA-April 23, 2008-Maxim Integrated Products (Pink OTC Markets: MXIM) introduces the MAX13041 ±80V fault-protected, high-speed, automotive CAN transceiver. This device provides an advanced interface between the protocol controller and the physical bus in a controller area network (CAN) node. Advanced power-management features enable this transceiver to minimize power consumption in ECU modules that are permanently supplied by a battery. Additionally, the MAX13041 provides an extended, ±80V fault-protected voltage range and ±12kV (Human Body Model) ESD protection on the CAN bus lines, making it ideal for robust +12V/+42V automotive and truck applications. Primarily intended for high-speed (up to 1Mbps), automotive CAN applications, it is also well suited for industrial applications.
To minimize current consumption, the MAX13041 features enhanced power management for clamp-30, always-on nodes. Five modes of operation provide different levels of functionality to optimize power consumption. In sleep mode, the ECU is completely powered down, thereby reducing current consumption to 18µA (typ). Upon local or CAN bus activity, the MAX13041 enables the on-board voltage regulator, restoring power to the entire clamp-30 node. Wake-up source recognition can be interrogated by the on-board microcontroller.
Designed for harsh operating conditions, this device features enhanced diagnostics and overtemperature protection. Capable of detecting local and remote bus failures, the MAX13041 features fail-safe modes to prevent damage to the device or interference with CAN-bus communication. Seven internal flags are used to indicate various fault conditions; five of these flags are available to the system CAN controller. The diagnostic features of the MAX13041, combined with its passive behavior in the absence of power, enable the construction of safe and reliable CAN nodes.
The MAX13041 conforms to the ISO 11898-2 specification, and it offers excellent EMC performance and ultra-low power consumption. Available in a lead-free, RoHS-compliant, 14-pin SO package, this device is fully specified over the -40°C to +125°C automotive temperature range. Prices start at $0.89 (1000-up, FOB USA).
