off by disabling the voltage regulator. That allows the total current consumption to drop
down to less than 100 µA.
When a reset occurs, due to false watchdog triggering, the TLE6263 automatically
switches from normal mode or receive-only mode respectively, to the V
mode. If a watchdog reset occurs in the V
In sleep mode a wake-up at any of the wake-up inputs as well as via the bus lines (CANH
or CANL) automatically sets the TLE 6263 in V
mode a wake-up is monitored by setting the output RxD low. This feature works as a flag,
to indicate a wake event to the microcontroller. To send and to receive messages, the
CAN-transceiver has to be set to normal operation mode by the microcontroller.
In case the IC shall directly be set back to sleep mode after a wake-up, an internal wake-
flip-flop has to be reseted via the SPI. Therefore IBIT1 has to be set high and then low
again by a second SPI transmission. A transition from the V
normal mode or receive-only mode respectively, automatically resets the wake-flip-flop.
6.2
The integrated low dropout voltage regulator is able to drive the internal loads (e.g. CAN-
circuit) as well as external 5V loads. Its output voltage tolerance is better than ± 2%. The
maximum output current is limited to 110 mA.
An external reverse current protection is recommended at the pin Vs 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 C
nevertheless it is recommended to use capacitors C
and therefore improve the reset behavior at input voltage transients.
To stabilize the internal supply a capacitor C
is required.
6.3
The TLE 6263 is optimized for low speed data transmission up to 125 kBaud in
automotive applications. Figure 4 shows the principle configuration of a CAN
network.Normally a differential signal is transmitted and received respectively. When a
bus wiring failure (see table 2) is detected the device automatically switches to a
dedicated CANH or CANL single-wire mode to maintain the communication if necessary.
Further a receive-only mode is implemented that allows a separate CAN node diagnosis.
