Single Wire CAN Transceiver
The 33897 series provides a physical layer for digital
communication 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 (SWCAN).
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 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 pin 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
• Under-voltage lockout prevents false data with low battery
