type package TLE6258-2G pg-dso-8 lin transceiver TLE6258-2G data sheet 3 rev. 2.1, 2007-08-08 features ? single-wire transceiver, suitable for lin protocol compatible to lin specification 1.2, 1.3 and 2.0 compatible to iso 9141 functions transmission rate up to 20 kbaud very low current consum ption in stand-by mode wake-up from bus short circuit proof to ground and battery overtemperature protection green product (rohs compliant) aec qualified description the single wire transceiver TLE6258-2G is a monolithic integrated circuit in a pg-dso-8 package. it works as an interface between the protocol controller and the physical bus. the TLE6258-2G is especially suitable to drive the bus line in lin systems in automotive and industrial appl ications. further it can be us ed in standard iso9141 systems. in order to reduce the current consumption the TLE6258-2G offers a stand-by mode. a wake-up caused by a message on the bus se ts the rxd output low until the device is switched to normal operation mode. 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 TLE6258-2G is designed to withstand the severe conditions of automotive applications.

data sheet 6 rev. 2.1, 2007-08-08 TLE6258-2G application information figure 3 state diagram for fail safe reasons the TLE6258-2G has already a pull-up resistor of 30 k ? implemented. to achieve the required timing s for the dominant to recessive transition of the bus signal an additional exte rnal termination resistor of 1 k ? is required. it is recommended to place this resistor in the master node. to avoid reverse currents from the bus line into the battery supply line in ca se of an unpowered node, it is recommended to place a diode in series to the external pu ll-up. for small systems (low bus capacitance) the emc performance of the system is supporte d by an additional ca pacitor of at least 1 nf in the master node (see figure 6 ). in order to reduce the current consumpti on the TLE6258-2G offers a stand-by mode. this mode is selected by switching the enable not (enn) input high (see figure 3 ). in the stand-by mode a wake-up caused by a message on the bus is indicated by setting the rxd output low. when ente ring the normal mode this wake-up flag is reset and the rxd output is released to transmit the bus data. toaea03451_1.vsd start up power up enn normal mode v cc low on power-up v cc enn rxd high low 1) high 3) on or off enn stand-by mode v cc high on or off enn wake up t > t wake 1) after wake-up via bus 3) after start up, v cc on high enn low enn low
