MC33897CTEF

The MC33897CTEF is a single wire CAN Transceiver 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). It operates directly from a vehicle's 12V battery system or a broad range of DC-power sources. It can operate at low or high (33.33 or 83.33kbps) 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.

• Wave shaping for low electromagnetic interference (EMI)
• Detects and automatically handles loss of ground
• Worst-case sleep mode current of only 60μA
• 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
