HS CAN Transceiver

High Speed CAN Transceiver

Modes of operation

• The transmitter is disabled and the data available on the TxD input is blocked.

•The normal-mode receiver is enabled.

• The RxD output pin indicates the data received by the normal-mode receiver.

• The bus biasing is connected to VCC/2.

• The RM input pin is active and changes the mode of operation to Normal-operating mode, if logical “low”.

• The TxD time-out function is disabled.

• The overtemperature protection is disabled.

• The undervoltage detection on VCC is active and changes the mode of operation to Forced-receive-only

mode in case of detection.

• The undervoltage detection on VIO is enabled and powers down the device in case of detection.

• Receive-only mode can only be entered when VCC (VCC > VCC(UV,R)) and VIO(VIO > VIO(UV,R)) are available.

Power-down state

Independent of the transmitter supply VCC and RM input pin the TLE9250X is powered down if the supply

voltage VIO < VIO(UV,R) (see Figure 4).

In the power-down state the differential input resistors of the receiver are switched off. The CANH and CANL

bus interface of the TLE9250X is floating and acts as a high-impedance input with a very small leakage current.

The high-ohmic input does not influence the “recessive” level of the CAN network and allows an optimized

EME performance of the entire HS CAN network. In power-down state the transceiver is an invisible node to

the bus.
