MC33897单线收发器

　　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.
