HI-3000, HI-3001, HI-3002 1Mbps Avionics CAN Transceiver with Low Power Standby Mode October 2015 PIN CONFIGURATIONS (Top Views) GENERAL DESCRIPTION TXD - 1 The HI-3000 is a 1 Mbps Controller Area Network (CAN) transceiver optimized for use in aerospace applications. It interfaces between a CAN protocol controller and the physical wires of the bus in a CAN network. Differential output amplitude and current drive capability are specifically enhanced to meet the needs of long cable runs typical of aerospace applications. 8 - STB HI-3000PSI HI-3000PST HI-3000PSM GND - 2 VDD - 3 5 - SPLIT TXD - 1 8 - STB HI-3001PSI HI-3001PST HI-3001PSM GND - 2 VDD - 3 o o All three devices are available in industrial -40 C to +85 C o o and extended -55 C to +125 C temperature ranges.

F) 6 - CANL 8 - PIN PLASTIC NARROW BODY SOIC A TXD dominant time-out feature also protects the bus from being driven into a permanent dominant state (socalled "babbling idiot") if pin TXD becomes permanently low due to application failure. The HI-3002 provides both the SPLIT and VIO supply voltage pins in a compact 16-pin QFN. 7 - CANH RXD - 4 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. In addition, the HI-3000 provides a SPLIT pin to give an output reference voltage of VDD/2 which can be used for stabilizing the recessive bus level when the split termination technique is used to terminate the bus. The HI-3001 is identical to the HI-3000 except the SPLIT pin is substituted with a VIO supply voltage pin. This allows the HI-3001 to interface directly with controllers with 3.3V supply voltages. 6 - CANL RXD - 4 The HI-3000 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. The device also has short circuit protection to +/-58V on CANH, CANL and SPLIT pins and ESD protection to +/- 6kV on all pins. 7 - CANH recessive bus level if split termination is used (HI-3000 SPLIT pin). VIO input on HI-3001 allows for direct interfacing with 3.3V controllers. Detection of permanent dominant on TXD pin (babbling idiot protection). High impedance allows connection of up to 120 nodes. Input levels compatible with 3.3V or 5V controllers. CANH, CANL and SPLIT pins short-circuit proof to +/-58V. Will not disturb the bus if unpowered. Extended temperature range and burn-in options for high reliability applications.

HI-3000 Functional Block Diagram HOLT INTEGRATED CIRCUITS 2 HI-3000, HI-3001, HI-3002 FUNCTIONAL DESCRIPTION OPERATING MODES The HI-3000 provides two modes of operation which are selectable via the STB pin. Table 1 summarizes the modes. due to an unpowered node with high leakage from the bus lines to ground), the split circuit will force the recessive voltage to VDD/2. INTERNAL PROTECTION FEATURES Table 1 - Operating Modes MODE Normal Standby Short-circuit protection STB pin Short-circuit protection is provided on the CANH, CANL and SPLIT pins. These pins are protected from ESD to over 6KV (HBM) and from shorts between -58V and +58V continuous, as specified in ISO 11898-5. The short circuit current is limited to less than 200mA typical. LOW HIGH TXD permanent dominant time-out Normal Mode Normal mode is selected by setting the STB pin to a LOW logic level (GND). In this mode, the transceiver transmits and receives data in the usual way from the CANH and CANL bus lines. The differential receiver converts the analog bus data to digital data which is output on the RXD pin (Note: the RXD output on HI-3001 is compatible with 3.3V controllers if the VIO pin is connected to a 3.3V supply). Standby Mode A timer circuit prevents the bus lines being driven into a permanent dominant state, which would result in a situation blocking all bus traffic. This could happen in the case of the TXD pin becoming permanently low due to a hardware or application failure. The timer is triggered by a negative edge on the TXD pin (start of dominant state). If the TXD pin is not set high (recessive state) after a typical time of 2ms, the transmitter outputs will be disabled, driving the bus lines into the recessive state. The timer is reset by a positive edge on the TXD pin. Note that the minimum TXD dominant time-out time, tdom = 300s, defines the minimum possible bit rate of 40kbit/s (the CAN protocol specifies a maximum of 11 successive dominant bits - 5 successive dominant bits immediately followed by an error frame). Standby Mode is selected by setting the STB pin to a HIGH logic level. In this mode, the transmitter is switched off and a low power differential receiver monitors the bus lines for activity. A dominant signal of more than 3ms will be reflected on the RXD pin as a logic LOW, where it may be detected by the host as a wake-up request. The device will not leave standby mode until the host forces the STB pin to a logic low. Fail-safe features SPLIT Circuit Pins TXD and STB will become floating if power is lost. This will prevent reverse currents via these pins. Pin TXD has a pull up in order to force a recessive level if pin TXD is left open. The SPLIT pin provides a stable VDD/2 DC voltage. This pin can be used to stabilize the recessive common mode voltage by connecting the SPLIT pin to the center tap of the split termination (see figure 7). In the case of a recessive bus voltage dropping below the ideal value of VDD/2 (e.g. HOLT INTEGRATED CIRCUITS 3 HI-3000, HI-3001, HI-3002 TIMING DIAGRAMS Timing Delays HIGH TXD LOW CANH CANL Dominant 0.9V VDIFF(BUS) = VCANH - VCANL 0.5V Recessive HIGH RXD 50% 50% LOW tdr(TXD) tdf(TXD) tdr(RXD) tdf(RXD) tProp1 tProp2 TXD dominant time-out feature transmitter enabled tdom(TXD) tRdom recessive TXD dominant HIGH LOW transmitter disabled CANH CANL HOLT INTEGRATED CIRCUITS 4 HI-3000, HI-3001, HI-3002 ABSOLUTE MAXIMUM RATINGS (Voltages referenced to GND = 0V) Supply Voltage, VDD, VIO : .....................................................................7V Current at Input pins ......................................................-100mA to +100mA DC Voltages at TXD, RXD and STB ..............................-0.5V to VDD +0.5V DC Voltages at CANH, CANL and SPLIT: ...............................-58V to +58V Internal Power Dissipation: ..............................................................900mW Electrostatic Discharge (ESD)1, All pins ..........................................+/- 6kV Operating Temperature Range: (Industrial).........................-40C to +85C (Hi-Temp) ........................-55C to +125C 2 Maximum Junction Temperature ......................................................175C Storage Temperature Range: ................................... -65C to +150C Reflow Soldering Temperature: ................................................. 260C NOTES: 1.
