TWIN CAN-Transceiver TLE 6253 Target 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 3,3V micro controllers Bus pins are short circuit proof to ground and battery voltage Over-temperature protection Very wide temperature range (- 40 C up to 150 C) P-DSO-16 Type Ordering Code Package TLE 6253 G TLE 6253 G V33 P-DSO-16 P-DSO-16 Description The CAN-transceiver TLE 6253 is a monolithic integrated circuit that is available as bare die as well as in a P-DSO-16 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 12). It works as an interface between the CAN protocol controller and the physical differential bus in both, 12 V and 24 V systems. The TLE 6253 offers three operation modes: normal, stand-by and receive-only mode. This can be controlled by the input pins INH and RM. 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 6253 is designed to withstand the severe conditions of automotive applications and provides excellent EMC performance. Data Sheet Version 1.03 1 2002-03-05

Application Information INH = 1 INH = 0 and RM = 1 Normal Mode INH = 0 RM = 1 RM = 0 RM = 1 Stand-by Mode INH = 0 and RM = 0 Receive-only Mode INH = 1 RM = 0 / 1 INH = 1 INH = 0 RM = 0 AED02924 Figure 4 Mode State Diagram The TLE 6253 G offers three different operation modes (see Figure 4), controlled by the INH and RM pin. The TLE 6253 G V33 has two different operation modes, normal and stand-by, controlled by the INH pin like in 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 transmitter. The receive only mode feature for the TLE 6253 G V33 is not available. The inhibit feature for this version works in the same way as for the 5V version. 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 6253 in normal mode. Data Sheet Version 1.03 6 2002-03-05
