achieve a low power consumption. All other functions are active as in the normal mode
(see Table 3). The CANL line is pulled-up to battery supply voltage via the RTL output
and CANH pulled to GND via RTH. A wake-up request via a CAN message on the bus
is immediately reported to the microcontroller by setting RxD=LOW. The wake pin WK
is not active in this mode. A power-on condition (
automatically switches the TLE 6266 to
drops below the specified limits (undervoltage reset), the transceiver is automatically
switched to
Cyclic Wake Modes
In the cyclic wake operation mode the lowest power consumption is achieved. This mode
consists of two states, the Cyclic HS ON and the Cyclic HS OFF mode. Everytime the
cyclic HS ON mode is entered (from all other modes), a long open window is started.
In the HS ON state the transmitter, receiver and all switches, except the HS3 switch, are
deactivated. The CANL line is pulled-up to battery supply voltage via the RTL output and
CANH pulled to GND via RTH. A wake-up via CAN bus message sets the RxD output to
LOW. Everytime the cyclic HS ON mode is entered , a long open window is started. If
there is no valid watchdog trigger or a PWM transition into the HS OFF state during this
time, a watchdog reset is activated. Only a correct trigger signal on the PWM pin causes
a transition into the cyclic HS OFF state. This is called the “failsafe PWM” feature.
In the HS OFF state, almost all functions of the IC are deactivated(also HS3-switch).
Only the wake-up input, the oscillator and the power-on reset circuit are activated. The
oscillator is used to realize the HS3-cyclic wake function.This automatically switches to
HS ON state after a programed time, to enabled HS3 (see Table 2).The CANL line is
pulled-up to battery supply voltage via the RTL output and CANH pulled to GND via RTH.
Only the wake up via CAN message sets the RxD to low (visible in HS ON state).
There are three possibilities to enter the cyclic HS ON mode from the HS OFF mode:
- the cyclic wake function
- a rising edge at the wake-up pin
