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
bat
stand-by
mode. If a watchdog reset occurs in the V
bat
stand-by mode the IC remains in this mode.
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
bat
stand-by mode. In the V
bat
stand-by 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
bat
stand-by mode to the
normal mode or receive-only mode respectively, automatically resets the wake-flip-flop.
6.2
Low Dropout Voltage Regulator
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
Q
≥
100 nF,
nevertheless it is recommended to use capacitors C
Q
≥
10 μF to buffer the output
voltage and therefore improve the reset behavior at input voltage transients.
To stabilize the internal supply a capacitor C
VI
≥
100 nF directly connected to the pin V
CI
is required.
6.3
CAN Transceiver
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. During normal and RxD-only mode, RTL is switched to V
CC
and RTH
to GND. During V
bat
stand-by and the cyclic wake mode, RTL is switched to V
S
and RTH
to GND.
