CAN-Transceiver
TLE 6250
Preliminary Data Sheet Features * CAN data transmission rate up to 1 MBaud * Suitable for 12 V and 24 V applications * Excellent EMC performance (very high immunity and very low emission) * Version for 5 V and 3.3 V micro controllers * Bus pins are short circuit proof to ground and battery voltage * Over-temperature protection * Very wide temperature range (- 40C up to 150C) Type TLE 6250 G TLE 6250 C TLE 6250 G V33 TLE 6250 C V33 Description The CAN-transceiver TLE 6250 is a monolithic integrated circuit that is available as bare die as well as in a P-DSO-8-3 package. The IC is optimized for high speed differential mode data transmission in automotive and industrial applications and is compatible to ISO/DIS 11898 (see page 10). It works as an interface between the CAN protocol controller and the physical differential bus in both, 12 V and 24 V systems. There are two versions available: one for 5 V logic and the other one for 3.3 V logic requiring additional supply via the V33V pin. The IC can be set to stand-by mode via an control input. In addition the 5 V-version offers a receive only mode feature to support diagnostic functions. The IC is based on the Smart Power Technology SPT which allows bipolar and CMOS control circuitry in accordance with DMOS power devices existing on the same monolithic circuit. The TLE 6250 is designed to withstand the severe conditions of automotive applications and provides excellent EMC performance.

Mode State Diagram (5V version)
Both, the TLE 6250 G as well as the TLE 6250 C offer three different operation modes (see Figure 4). In the normal mode the device is able to receive and to transmit messages whereas in the receive-only mode signals at the TxD input are not transmitted to the CAN bus. The receive-only mode can be used for diagnostic purposes as well as to prevent the bus being blocked by a faulty permanent dominant TxD input signal. The stand-by mode is a low power mode that disables both, the receiver as well as the transmit TLE 6250 G V33 and TLE 6250 C V33 the receive only mode feature is not available. The inhibit feature for this versions works in the same way as for the 5V versions. In case the receive-only feature is not used the RM pin has to be left open. When the stand-by mode is not used the INH pin has to be connected to ground level in order to switch the TLE 6250 in normal mode.
