AMIS−41683 is identical to the AMIS−41682 but has a true 3.3 V digital interface to the CAN controller. The device provides differential transmit capability but will switch in error conditions to a single−wire transmitter and/or receiver. Initially it will be used for low speed applications, up to 125 kB, in passenger cars. Both AMIS−41682 and AMIS−41683 are implemented in I2T100 technology enabling both high−voltage analog circuitry and digital functionality to co−exist on the same chip.

The different wiring failures are depicted in Figure 4. The figure also indicates the effect of the different wiring failures on the transmitter and the receiver. The detection circuit itself is not depicted. The differential receiver threshold voltage is typically set at 3 V (VCC = 5 V). This ensures correct reception with a noise margin as high as possible in the normal operating mode and in the event of failures 1, 2, 4, and 6a. These failures, or recovery from them, do not destroy ongoing transmissions. During the failure, reception is still done by the differential receiver and the transmitter stays fully active. To avoid false triggering by external RF influences the single−wire modes are activated after a certain delay time. When the bus failure disappears for another time delay, the transceiver switches back to the differential mode. When one of the bus failures 3, 5, 6, 6a, and 7 is detected, the defective bus wire is disabled by switching off the affected bus termination and the respective output stage. A wake−up from sleep mode via the bus is possible either by way of a dominant CANH or CANL line. This ensures that a wake−up is possible even if one of the failures 1 to 7 occurs. If any of the wiring failure occurs, the output signal on pin ERR will become low. On error recovery, the output signal on pin ERR will become high again. During all single−wire transmissions, the EMC performance (both immunity and emission) is worse than in the differential mode. The integrated receiver filters suppress any HF noise induced into the bus wires. The cut−off frequency of these filters is a compromise between propagation delay and HF suppression. In the single−wire mode, LF noise cannot be distinguished from the required signal. AMIS−41682 is a fault tolerant CAN transceiver which works as an interface between the CAN protocol controller and the physical wires of the CAN bus (see Figure 2). It is primarily intended for low speed applications, up to 125 kB, in passenger cars. The device provides differential transmit capability to the CAN bus and differential receive capability to the CAN controller. The AMIS−41683 has open−drain outputs (RXD and ERR Pins), which allow the user to use external pullup resistors to the required supply voltage; this can be 5 V or 3.3 V. To reduce EME, the rise and fall slope are limited. Together with matched CANL and CANH output stages, this allows the use of an unshielded twisted pair or a parallel pair of wires for the bus lines. The failure detection logic automatically selects a suitable transmission mode, differential or single−wire transmission. Together with the transmission mode, the failure detector will configure the output stages in such a way that excessive currents are avoided and the circuit returns to normal operation when the error is removed. A high common−mode range for the differential receiver guarantees reception under worst case conditions and together with the integrated filter the circuit realizes an excellent immunity against EMS. The receivers connected to pins CANH and CANL have threshold voltages that ensure a maximum noise margin in single−wire mode. A timer has been integrated at Pin TXD. This timer prevents the AMIS−41682 from driving the bus lines to a permanent dominant state. Failure Detector The failure detector is fully active in the normal operating mode.

Different Types of Wiring Failure Low Power Modes The standby mode will react the same as the sleep mode but with a high−level on pin INH. The power−on standby mode is the same as the standby mode with the battery power−on flag instead of the wake−up interrupt signal on Pin ERR. The output on Pin RXD will show the wake−up interrupt. This mode is only for reading out the power−on flag. Wake−up request is detected by the following events: The transceiver provides three low power modes, which can be entered and exited via Pins STBB and EN (see Figure 5). (Go−to−sleep mode is only a transition mode.) The sleep mode is the mode with the lowest power consumption. Pin INH is switched to high−impedance for deactivation of the external voltage regulator. Pin CANL is biased to the battery voltage via Pin RTL. If the supply voltage is provided, Pins RXD and ERR will signal the wake−up interrupt signal. http://onsemi.com 6 AMIS−41682, AMIS−41683 circuit can still go to another low−power mode. After this time the circuit goes to the sleep−mode. In case of a wake up request (from BUS or WAKE Pin) during this transition time, the wake−up request has higher priority than go−to−sleep and INH will not be deactivated. • Local Wake−up: Rising or falling edge on input WAKE (levels maintained for a certain period). • Remote Wake−up from CAN Bus: A message with five consecutive dominant bits. On a wake−up request the transceiver will set the output on Pin INH high which can be used to activate the external supply voltage regulator. Note: Pin INH is also set similarly as an after wake up event by VBAT voltage being below the battery power on flag level. (See FLAG_VBAT in Figure 5) If VCC is provided, the wake−up request can be read on the ERR or RXD outputs so the external microcontroller can wake−up the transceiver (switch to normal operating mode) via Pins STB and EN. In the low power modes the failure detection circuit remains partly active to prevent increased power consumption in the event of failures 3, 3a, 4, and 7. The go−to−sleep−mode is only a transition mode. The Pin INH stays active for a limited time. During this time the Behavior in Case of Missing Supplies If VCC is below the threshold level FLAG_VCC, the signals on pins STB and EN will internally be set to low-level to provide fail safe functionality. In this way, a low-power mode will be forced in case of missing/failing VCC supply. Similarly, missing/failing VBAT supply – i.e. VBAT being below FLAG_VBAT level - will lead to a fail-safe behavior of the transceiver by forcing a low-power mode. A forced low-power in case of missing supplies guarantees that the transceiver will in no way disturb the other CAN nodes when the local electronic unit looses ground or battery connection.

If the junction temperature exceeds a maximum value, the transmitter output stages are disabled and flagged on the ERR pin. Because the transmitter is responsible for the major part of the power dissipation, this will result in reduced power dissipation and hence a lower chip temperature. All other parts of the IC will remain operating. The Pins CANH and CANL are protected against electrical transients that may occur in an automotive environment. After power−on (VBAT switched on) the signal on Pin INH will become high and an internal power−on flag will be set. This flag can be read in the power−on standby mode via pin ERR (STB = 1; EN = 0) and will be reset by entering the normal operating mode.
