1 / 13 page  GENERAL DESCRIPTION The HI-5000 is a 1 Mbps Controller Area Network (CAN) transceiver. It interfaces between a CAN protocol con- troller and the physical wires of the bus in a CAN network. The HI-5000 supports two modes of operation: Normal Mode and Standby Mode. The Standby Mode is a very low-current mode which continues to monitor bus activity and allows an external controller to manage wake-up. In addition, the HI-5000 provides a SPLIT pin to give an output reference voltage of VDD/2 which can be used for stabilizing the re- cessive bus level when the split termination technique is used to terminate the bus. A TXD dominant time-out feature also protects the bus from being driven into a permanent dominant state (so- called “babbling idiot”) if pin TXD becomes permanently low due to application failure. The device also has short circuit protection to +/-58V on CANH, CANL and SPLIT pins and ESD protection to +/- 6kV on all pins. The HI-5001 is identical to the HI-5000 except the SPLIT pin is substituted with a VIO supply voltage pin. This al- lows the HI-5001 to interface directly with controllers with 2.5V or 3.3V supply voltages. The HI-5002 provides both the SPLIT and Differential output amplitude and current drive capability are specifically enhanced to meet the needs of long cable runs typical in many applications such as industrial auto- mation. Superior common-mode receiver performance makes the device especially suitable for applications where ground reference voltages may vary from point to point over long distances along the CAN bus. VIO supply voltage pins in a compact 16-pin QFN. All three devices are available in industrial -40 C to +85 C temperature ranges. “RoHS compliant” lead-free options are also available. oo FEATURES Compatible with ISO 11898-5 standard. Signaling rates up to 1Mbit/s. Internal VDD/2 voltage source available to stabilize the recessive bus level if split termination is used (HI-5000 SPLIT pin). VIO input on HI-5001 allows for direct interfacing with 2.5V or 3.3V controllers. Detection of permanent dominant on TXD pin (babbling idiot protection). High impedance allows connection of up to 120 nodes. CANH, CANL and SPLIT pins short-circuit proof to +/-58V. Will not disturb the bus if unpowered. · · · · · · · · PIN CONFIGURATIONS (Top Views) September 2011 ( 5000 Rev.
