• Manufacturer Part Number: TLE6251-3G
• Manufacturer: Infineon Technologies

Specifications of TLE6251-3G

• Packages: PG-DSO-14
• Transmission Ratemax: 1.0 Mbit/s
• Quiescent Current (max.): < 30 µA @ 5V standby
• Bus Wake-up Capability: Yes
• Additional Features: NSTB, WK, EN, NERR, INH, Vio, no SPLIT PIN
• Wake-up Inputs: Bus wake-up + wake-up pin

In Sleep mode the power supply
the CAN bus or the local Wake-Up pin, shifts the device from Sleep mode into Stand-By mode.
The following operations mode are available on the TLE6251-3G:
•
•
•
•
•
Depending on the operation mode, the output driver stage, the receiver stage and the bus biasing are active or
inactive.
with the related status of the INH pin and the bus biasing.

In Normal Operation mode the HS CAN transceiver TLE6251-3G sends the serial data stream on the TxD pin to
the CAN bus while at the same time the data available on the CAN bus is monitored on the RxD output pin. In
Normal Operation mode all functions of the TLE6251-3G are active:
•
•
•
•
•
•
•
•
•
The HS CAN transceiver TLE6251-3G enters Normal Operation mode by setting the mode selection pins EN and
NSTB to logical “High” (see
5.2
The Receive-Only mode can be used to test the connection of the bus medium. The TLE6251-3G can still receive
data from the bus, but the output stage is disabled and therefore no data can be sent to the CAN bus. All other
functions are active:
•

Go-To-Sleep Command
The output stage is active and drives data from the TxD to the CAN bus.
The normal receiver unit is active and provides the data from the CAN bus to the RxD pin.
The low power receiver and the bus Wake-Up function is inactive.
The local Wake-Up pin is disabled.
The INH pin is connected to
The RxD pin is “Low” for a “Dominant” bus signal and “High” for a “Recessive” bus signal”
The bus basing is set to
The failure detection is active and failures are indicated at the NERR pin. (see
The under-voltage detection on the all 3 power supplies
The output stage is disabled and data which is available on the TxD pin will be blocked and not communicated
to the CAN bus.
The normal receiver unit is active and provides the data which is available on the CAN bus to the RxD pin.
The INH pin is connected to
The RxD pin is “Low” for a “Dominant” bus signal and “High” for a “Recessive” bus signal.
The bus biasing is set to
