Pin Definitions and Functions (cont’d)
Symbol Function
RTH
Termination resistor output; connected to CANH bus-line
via termination resistor (500 Ω < RRTH < 16 kΩ), controlled by
internal failure management
RTL Termination resistor output; connected to CANL bus-line
via termination resistor (500 Ω < RRTL < 16 kΩ), controlled by
internal failure and mode management
VCC Supply voltage input; +5 V, block to GND directly at the IC
with ceramic capacitor
CANH
CAN bus line H; HIGH: dominant state
CANL
CAN bus line L; LOW: dominant state
GND
Ground
VS Battery voltage supply input; block to GND directly at the
IC with ceramic capacitor

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 via a dominant CANH or CANL
line. This ensures that a wake-up is possible even if one of the failures 1 to 7 occurs.

A current limiting circuit protects the CAN transceiver output stages from damage by
short-circuit to positive and negative battery voltages.
The CANH and CANL pins are protected against electrical transients which may occur
in the severe conditions of automotive environments.
www.DTathaSeheterta4Un.scommitter output stages generate the majority of the power dissipation. Therefore
they are disabled if the junction temperature exceeds the maximum value. This
effectively reduces power dissipation, and hence will lead to a lower chip temperature,
while other parts of the IC can remain operating. In temperature shut-down condition the
TLE 6254-3 G is still able to receive CAN-bus messages.
