1. Overview:

️· Function: The B10011S is a CAN transceiver designed for robust serial data interchange in harsh environments. It's specifically adapted for a "special high-level, low-speed transmission system."
️· Focus: Designed for high immunity to ground offsets and interference, rather than power efficiency or minimal components.
️· Error Detection: Includes an error detection scheme to quickly notify the controller of bus faults, enabling search cycles or disabling the station.

2. Features:

️· CAN Transceiver: Designed for CAN communication.
️· High Immunity: Excellent immunity to ground offsets and interference.
️· Error Detection: Integrated error detection with an open-collector output driver for error signaling.
️· Multiple Operation Modes: Four operating modes controlled by A sel and B sel inputs (see Table "Operating Modes").
️· Dominant/Recessive State Control: Error signal (ER) can be generated in either the recessive or dominant state.
️· Level Shifting: Input filter section acts as a level shifter (approximately 1-3.3V range) from the 5V internal supply.
️· Fast Response: Transition times are fast, designed for data integrity.

3. Application & Recommendations (Crucial for Success):

️· Filtering: A 2-RC input filter is *required* for 125 kbit/s operation and should not be modified.
️· Power Filtering: A power filter and overvoltage clamp are *highly recommended* to prevent transmission errors.
️· Grounding: *Critical!* Battery ground and filter ground *must* be separate and properly connected. Filter ground connection to pin 8 is especially important. A 0.1 µF capacitor may be necessary on the star-quad cable.
️· Thermal Management: Keep voltage divider and driving resistors away from the IC to prevent overheating.
️· Capacitance: Line capacitance to ground should not exceed 200 pF/m, with a maximum of 6 nF total.
️· Layout: Carefully plan PCB layout and implement EMC design to minimize noise and interference.
️· Level Investigations: This circuit was tested with two B10011S on a bus line, one in the recessive state.

4. Ordering Information:

️· B10011S-MFPG1Y: SO16 package (Taped and reeled, Pb-free)
️· B10011S-MFPG3Y: SO16 package (Taped and reeled, Pb-free)

5. Key Specifications & Considerations (From the Text):

️· Supply Voltage (V DD): 5V (internal)
️· Comparator Input Range: ~1V to ~3.3V
️· Comparator Offset Voltage: ≤ 10 mV
️· Data Rate: Designed for 125 kbit/s (but the filter can be adapted for 250 kbit/s)
️· Transition Times: Fast, with a faster transition from recessive to dominant.
️· Capacitance limits: Crucially, keep line capacitance within the specified limits.

Notes and Important Considerations:

️· This is not a plug-and-play component. Proper application requires careful attention to grounding, filtering, and layout as detailed in the datasheet.
️· The application notes are *essential* for successful operation. Ignoring them can lead to unreliable communication.
️· The "star quad" cable, battery ground and filter ground separation is critical for performance.
️· The datasheet mentions limitations. The controller must carry out checks for fault recognition.
