HS CAN Transceiver

High Speed CAN Transceiver

Modes of operation

• The RxD output pin is permanently set to logical “high”.

• The bus biasing is floating.

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

and VCC (VCC > VCC(UV,R)) is available.

• The overtemperature protection is disabled.

• The undervoltage detection on VCC is disabled. In Power-save mode the device can operate without the

transmitter supply VCC.

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

Power-down state

Independent of the transmitter supply VCC and NEN input pin the TLE9250V 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 TLE9250V 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.
