Normally a differential signal is transmitted or received respectively. When a bus wiring failure (see table 4) is detected the device automatically switches to a dedicated CANH or CANL single-wire mode to maintain the communication if necessary. Therefore it is equipped with one differential receiver and four single ended comparators (two for each bus line). To avoid false triggering by external RF influences the single wire modes are activated after a certain delay time. As soon as the bus failure disappears the transceiver switches back to differential mode after another time delay. The bus failures are monitored via the diagnosis protocol of the SPI. Therefore it is possible to distinguish 6 CAN bus failures or failure groups on the bits 8 to 13 (see table 3). To reduce EMC caused by the transceiver the dynamic slopes of the CANL and CANH signals are both limited and symmetric. This allows the use of an unshielded twisted or parallel pair of wires for the bus. During single-wire transmission (bus-failure) the EMC performance of the system is degraded from the differential mode. The differential receiver threshold is set to typ. -2.8 V. This ensures correct reception in the normal operation mode as well as in the failure cases 1, 2, 3a and 4 with a noise margin as high as possible. 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 output stage. The CAN-transceiver offers three different operation modes that are controlled via the SPI: the normal operation mode, Receive-only mode and Vbat stand-by mode. Please see the state diagram (figure 3). In the Vbat stand-by mode the RTL output voltage is switched to VS. In case of a wake-up via the bus lines or one of the bus lines respectively, the TLE 6262 automatically sets the RxD output LOW. To send respectively receive messages the CAN-transceiver can now be set in normal operation mode or receive-only mode by the microcontroller. When a reset occurs the transceiver circuit is automatically switched to Vbat-stand-by mode because the SPI input bits are automatically set LOW for this event. A thermal shutdown of the CAN-transceiver circuit is monitored via the SPI diagnosis bit 15. 7 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G Start Up Power Up Normal Mode NSTB 1 ENT ENT 1 0 V CC ON ENT NSTB 0 ENT 0 NSTB ENT V CC ON 1 1 NSTB ENT or VCC 1 NSTB VCC RxD-Only NSTB 1 NSTB ENT NSTB 0 or VRT 0 0 VRT Vbat Stand-By NSTB 0 1 ENT 0 VCC ON 0 1 Go- To-Sleep Mode NSTB 0 ENT 1 V CC ON ENT 1 Figure 3: State Diagram Low Dropout Voltage Regulator The TLE 6262 is able to drive external 5V loads up to 45 mA. Its output voltage tolerance is less than ± 2%. In addition the regulator circuit drives the internal loads like the CANtransceiver circuit. An external reverse current protection is recommended to prevent the output capacitor from being discharged by negative transients or low input voltage. Stability of the output voltage is guaranteed for output capacitors CVCC ³ 100 nF. Nevertheless a lot of applications require a much larger output capacitance to buffer the output voltage in case of low input voltage or negative transients. Furthermore the due function of e.g. the reset and 3V-supervisor circuit are supported by a larger output capacitance because of their reaction times. Therefore a output capacitance CVCC ³ 10 µF is recommended. 8 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G SPI (serial peripheral interface) The 16-bit wide programming word or input word (see table 1) is read in via the data input DI, and this is synchronized with the clock input CLK supplied by the µC. The diagnosis word appears synchronously at the data output DO (see table 3). The transmission cycle begins when the chip is selected by the chip select not input CSN (H to L). After the CSN input returns from L to H, the word that has been read in becomes the new control word. The DO output switches to tristate status at this point. For details of the SPI timing please refer to figure 3 to 7. Oscillator All internal delay times are referring to the internal oscillator frequency, which is set by an external resistor from pin OSC to GND. The oscillator frequency and the resulting internal cycling time can be calculated by the equations: 9 28, 45 ´10 [ Hz W ] f OSC = ----------------------------------------R OSC 32 t CYL = -----------f OSC Window Watchdog, Reset and 3V-Supervisor When the output voltage VCC exceeds the reset threshold voltage VRT the reset output RO is switched HIGH after a delay time of 16 cycles. This is necessary for a defined start of the microcontroller when the application is switched on. As soon as an under-voltage condition of the output voltage (VCC < VRT) appears, the reset output RO is switched LOW again. The LOW signal is guaranteed down to an output voltage VCC ³ 1V. Please refer to fig.11, reset timing diagram. Should the output voltage fall short of the 3V-supervisor threshold VST an internal flipflop is set LOW. The SPI diagnosis bit 7 monitors this. In normal operation this flip-flop has to be activated via the SPI input bit 7. This feature is useful e.g. to monitor that the RAM data of the microcontroller might be damaged or the application is connected to VS the first time. After the above described delayed reset (LOW to HIGH transition of RO) the window watchdog circuit is started by opening a long open window of 32 cycles. Now the microcontroller has to service a watchdog trigger signal via the SPI interface (input bit 0). A watchdog trigger is detected as a falling edge by sampling for 2 cycles a HIGH followed by 2 cycles LOW of the SPI input bit 0. The long open window ensures a simple and fast 9 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G synchronization of the TLE 6262 watchdog timing to the watchdog services of the microcontroller. After the first trigger the watchdog has to be serviced by meeting an open window of 20 cycles that follows a closed window of 12 cycles. A correct watchdog service immediately results in starting the next closed window. Please refer to fig. 10, watchdog timing diagram. If the trigger signal does not meet the open window (trigger to early or to late) the reset output RO is set LOW for a period of 4 cycles. Afterwards a long open window is started again. In addition, the SPI diagnosis bit 2 is set HIGH to monitor a watchdog reset. Both, the undervoltage reset and the watchdog reset are setting all SPI input bits LOW. To avoid a cyclic wake-up of the microcontroller in low power mode (sleep mode) the watchdog circuit can be automatically disabled at low output currents (ICC < ICCWD). To activate this feature the SPI input bit 8 has to be set HIGH. In this under-current mode the low side switches are switched off automatically by the TLE 6262 to guarantee failsave operation of the application. When the microcontroller returns back to normal mode (ICC > ICCWD) the first closed window is transformed to an open window so that the total open window time is 32 cycles. This ensures a more simple and fast synchronization of the TLE 6262 watchdog timing to the watchdog services of the microcontroller. Flash program mode To disable the watchdog feature a flash program mode is available. This mode is selected by applying a voltage of 6.8V < VPWM < 7.2V at pin PWM. This is useful e.g. if the flash-memory of the micro has to be programmed and therefore a regular watchdog triggering is not possible. If the SPI is required in the flash program mode to change e.g. the mode of the TLE6262 the first input telegram has to be “00000000”. High Side Switch 1 The high side output OUTH1 is able to switch loads up to 250 mA. Its on-resistance is 1.0 W typ. @ 25°C. This switch can be controlled either via the PWM input or the SPI input bit 1. When the input PWM is used it has to be enabled by setting the SPI input bit 11 HIGH. In case of both control inputs being active the PWM signal is masked by the SPI signal (see fig. 8, High Side Switch 1 Timing Diagram). The SPI diagnosis bit 14 monitors a thermal shutdown of the switches, whereas bit 0 flags a thermal prewarning. By this the microcontroller is able to reduce the power dissipation of the TLE 6262 by switching off functions of minor priority before the temperature threshold of the thermal shutdown is reached. Further OUTH1 is protected against short circuit and overload. The SPI diagnosis bit 1 indicates an overload of OUTH1. As soon as the under-voltage condition of the supply voltage is met (VS < VUVOFF), the switches are automatically disabled by the under-voltage lockout circuit. 10 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G This is flagged by the SPI diagnosis bit 3. Moreover the switches are disabled when a reset occurs. High Side Switch 2 The high side output OUTH2 is able to switch loads up to 250 mA. Its on-resistance is 1.0 W typ. @ 25°C. This switch is controlled via the SPI input bit 2. The SPI diagnosis bit 14 monitors a thermal shutdown of the switches, whereas bit 0 flags a thermal prewarning. By this the microcontroller is able to reduce the power dissipation of the TLE 6262 by switching off functions of minor priority before the temperature threshold of the thermal shutdown is reached. As soon as the under-voltage condition of the supply voltage is met (VS < VUVOFF), the switches are automatically disabled by the under-voltage lockout circuit. This is flagged by the SPI diagnosis bit 3. Moreover the switches are disabled when a reset occurs. High Side Switch 3 The high side output OUTH3 is able to switch loads up to 150 mA. Its on-resistance is 1.5 W typ. @ 25°C. This switch is controlled via the SPI input bits 3 and 4. To supply external wake-up circuits in low power mode (sleep mode or Vbat-stand-by mode), the output OUTH3 can be periodically activated by the internal oscillator circuit. For activating this feature the SPI input bits 3 and 4 have to be set HIGH. The autotiming period is 128 internal cycle times; the on-time is 2 cycles. In case of a watchdog reset the autotiming period may be shorter. The SPI diagnosis bit 14 monitors a thermal shutdown of the switches, whereas bit 0 flags a thermal prewarning. By this the microcontroller is able to reduce the power dissipation of the TLE 6262 by switching off functions of minor priority before the temperature threshold of the thermal shutdown is reached. As soon as the under-voltage condition of the supply voltage is met (VS < VUVOFF), the switches are automatically disabled by the under-voltage lockout circuit. This is flagged by the SPI diagnosis bit 3. Moreover the switches are disabled when a reset occurs. Low Side Switches 1/2 The two low side outputs OUTL1 and OUTL2 are able to switch loads up to 100 mA. Their on-resistance is 1.5 W (typ.) @ 25°C. This switches are controlled via the SPI input bits 5 and 6. In case of high inrush currents a built in zener circuit (typ. 37 V) activates the switches to protect them. The SPI diagnosis bit 14 monitors a thermal shutdown of the switches, whereas bit 0 flags a thermal prewarning. By this the microcontroller is able to reduce the power dissipation of the TLE 6262 by switching off functions of minor priority before the temperature threshold of the thermal shutdown is reached. The SPI diagnosis bits 5/6 11 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G are giving a feedback about current status of OUTL1/OUTL2. As soon as the undervoltage condition of the supply voltage is met (VS < VUVOFF), the switches are automatically disabled by the under-voltage lockout circuit. This is flagged by the SPI diagnosis bit 3. In addition the outputs OUTL1 and OUTL2 are also disabled when the watchdog is switched off in undercurrent state or when a reset occurs. 12 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G Table 2 Table 3 Input Data Protocol Diagnosis Data Protocol BIT BIT 15 not used 15 Thermal Shutdown Transceiver 14 not used 14 Thermal Shutdown Switches 13 not used 13 CAN Failure 2 and 4 12 not used 12 CAN Failure 1 and 3a 11 PWM Enable 11 CAN Failure 6 10 CAN Enable Transmit 10 CAN Failure 6a 9 CAN Not Stand-By 9 CAN Failure 6a, 5 and 7 8 Watchdog Control 8 CAN Failure 3 7 Supervisor Enable 7 Vcc < 3V 6 LS-Switch 2 6 Status LS2 5 LS-Switch 1 5 Status LS1 4 HS3 Auto Timing 4 not used 3 HS-Switch 3 3 Vs Undervoltage Lockout 2 HS-Switch 2 2 Window Watchdog Reset 1 HS-Switch 1 1 Overload HS1 0 Watchdog Trigger 0 Temperature Prewarning H = ON L = OFF H = ON L = OFF 13 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G Table 4 CAN bus line failure cases (according to ISO 11519-2) failure # failure description 1 CANL line interrupted 2 CANH line interrupted 3 CANL shorted to Vbat, CANL > 7.2 V 3a (no ISO failure) CANL shorted to Vcc; 3.2 V < CANL < 7.2 V 4 CANH shorted to GND 5 CANL shorted to GND 6 CANH shorted to Vbat; CANH > 7.2 V 6a (no ISO failure) CANH shorted to Vcc; 1.8 V < CANH < 7.2 V 7 CANL shorted to CANH 14 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G 2 Electrical Characteristics 2.1 Absolute Maximum Ratings Parameter Symbol Limit Values Unit Remarks min. max. -0.3 28 V – -0.3 40 V tp< 0.5s; tp/T < 0.1 -0.3 5.5 V -10 28 V -40 40 V VS >0 V tp< 0.5s; tp/T < 0.1 -0.3 VCC V 0 V < VS < 24 V 0 V < VCC < 5.5 V V 0 V < VS < 24 V 0 V < VCC < 5.5 V V 0 V < VS < 24 V 0 V < VCC < 5.5 V Voltages Supply voltage Supply voltage Regulator output voltage CAN input voltage (CANH, CANL) CAN input voltage (CANH, CANL) VS VS VCC VCANH/L VCANH/L Logic input voltages (DI, CLK, VI CSN, OSC, PWM, TxD) +0.3 Logic output voltage (DO, RO, RxD) VDO/RO/RD -0.3 VCC Termination input voltage (RTH, RTL) VTL /TH Electrostatic discharge voltage at pin CANH, CANL VESD -4000 4000 V human body model; C = 100pF, R = 1.5kW Electrostatic discharge voltage VESD -2000 2000 V human body model; C = 100pF, R = 1.5kW ICC IOUTH1 IOUTH2 IOUTH3 IOUTL1 IOUTL2 – – A internally limited *) 0.3 A *) internally limited -0.7 0.3 A tp< 0.5s; tp/T < 0.1 -0.5 0.2 A tp< 0.5s; tp/T < 0.1 -0.2 0.4 A tp< 0.5s; tp/T < 0.1 -0.2 0.4 A tp< 0.5s; tp/T < 0.1 +0.3 -0.3 VS +0.3 Currents Output current; Vcc Output current; OUTH1 Output current; OUTH2 Output current; OUTH3 Output current; OUTL1 Output current; OUTL2 15 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G 2.1 Absolute Maximum Ratings (cont’d) Parameter Symbol Limit Values Unit Remarks min. max. -40 150 °C – -50 150 °C – Temperatures Junction temperature Storage temperature Tj Tstg Note: Maximum ratings are absolute ratings; exceeding any one of these values may cause irreversible damage to the integrated circuit. 16 version: 2.03 date: 2002-03-20 Final Data TLE 6262 G 2.2 Operating Range Parameter Symbol Limit Values min.
