Technical Data
Single Wire CAN Transceiver
The 33897 Series provides a physical layer for digital
communications purposes using a Carrier Sense Multiple Access/
Collision Resolution (CSMA/CR) data link operating over a single
wire medium. This is more commonly referred to as Single Wire
Controller Area Network (CAN).
The 33897 Series operates directly from a vehicle's 12 V battery
system or a broad range of DC-power sources. It can operate at
either low or high (33.33 kbps or 83.33 kbps) data rates. A high-
voltage wake-up feature allows the device to control the regulator
used in support of the MCU and other logic. The device includes a
control terminal that can be used to put the module regulator into
Sleep mode. The presence of a defined wake-up voltage level on the
bus will reactivate the control line to turn the regulator and the system
back on.
The device complies with the GMW3089v2.4 General Motors
Corporation specification.
Features
• Waveshaping for Low Electromagnetic Interference (EMI)
• Detects and Automatically Handles Loss of Ground
• Worst-Case Sleep Mode Current of Only 60 µA
• Current Limit Prevents Damage Due to Bus Shorts
• Built-In Thermal Shutdown on Bus Output
• Protected Against Vehicular Electrical Transients
• Undervoltage Lockout Prevents False Data with Low Battery
• Pb-Free Packaging Designated by Suffix Code EF
