data sheet 2 rev. 1.01 2018-01-09 TLE9252V high-speed can fd transceiver overview decription the TLE9252V is a transceiver designed for hs can netw orks up to 5 mbit/s in automotive and industrial applications. as an interface betw een the physical bus layer and the can protocol controller, the TLE9252V drives the signals to the bus and pr otects the microcontroller against interferences generated within the network. based on the high symmet ry of the canh and canl signals, the TLE9252V provides very low electromagnetic emission allowing the operation without a common mode choke. the non-low power modes (normal-operating mode and receive-only mode) and lo w power modes (sleep mode and stand-by mode) are optimized for reduced current consumption based on the required functionality. even in sleep mode with a quiescent current below 25 a over the full temperature range, the TLE9252V is able to detect a wake-up pattern (wup) on the hs can bus. the v io voltage reference input is used to support 3.3 v and 5 v supplied microcontrollers. the TLE9252V is in tegrated in an rohs compliant p g-dso-14 or pg-tson-14 package and fulfills the requirements of the iso11898-2 (2016). type

pin symbol function data sheet 8 rev. 1.01 2018-01-09 TLE9252V high-speed can fd transceiver high-speed can functional description 4 high-speed can functional description hs can is a serial bus system which connects microcon trollers, sensors and actuators for real-time control applications. the use of the controller area network (abbreviated can) within road vehicles is described by the international standard iso 11898. according to the 7-layer osi reference model the physical layer of a hs can bus system specifies the data transmission from one can node to all other available can nodes within the network. the physical layer specification of a can bus system includes all electrical specifications of a can network. the can transceiver is part of the physical layer specification. the tle 9252v supports both bus wake-up pattern (wup) functionality and local wake-up as defined by the iso 11898 standard. additionally, the TLE9252V supports can flexible data ra te (can fd) transmission up to 5 mbit/s. figure 3 high-speed can bus signals and logic signals txd v io t t v cc canh canl t v cc v diff rxd v io t v io = digital supply voltage v cc = transmitter supply voltage

high-speed can fd transceiver high-speed can functional description the TLE9252V is a high-speed can transceiver operating as an interface between th e can controller and the physical bus medium. a hs can network is a two wire, differential network which allows data transmission rates up to 5 mbit/s. the characteristic for a hs ca n network are the two signal states on the can bus: ?dominant? and ?recessive? (see figure 3 ). the canh and canl pins are the interface to the can bus and operate as an input and output. the rxd and txd pins ar e the interface to the micr ocontroller. the txd pin is the serial data input from the can controller. the rxd pin is the serial data output to the can controller. the hs can transceiver TLE9252V include s a receiver and a transmitter unit , allowing the transceiver to send data to the bus medium and monitors the data from th e bus medium at the same time. the hs can transceiver TLE9252V converts the serial data stream which is availa ble on the transmit data in put txd, into a differential output signal on the can bus, prov ided by the canh and canl pins. the receiver stage of the TLE9252V monitors the data on the can bus and converts it to a serial, single-ended signal on the rxd output pin. a logical ?low? signal on the txd pin creates a ?dominant? signal on the can bus, followed by a logical ?low? signal on the rxd pin (see figure 3 ). the feature, broadcasting data to the can bus and listening to the data traffic on the can bus simultaneously is essential to support the bit-to-bit arbitration within can networks. the voltage levels for hs can transceivers are defined in iso 11898-2. whether a data bit is ?dominant?

signal on the txd pin might have its root cause in a locked- up microcontroller or in a short circuit on the printed circuit board, for example. in normal-operating mode, a logical ?low? signal on the txd pin for the time t > t txd_to enables the txd time-out feature and the TLE9252V disables the transmitter (see figure 26 ) and sets the nerr output pin to lo gical ?low?. the receiver is still active and the data on the bus continues to be monitored by the rxd output pin. figure 26 txd time-out function table 3 logical inputs when unconnected input signal default state comment txd ?high?

to logical ?high?. 6.6 overtemperature protection the TLE9252V has an integrated overtemperature detection to protect the TLE9252V against thermal overstress of the transmitter. the ov ertemperature protection is active in normal-operating mode and is disabled in all other modes. the temperatur e sensor provides one temperature threshold: t jsd .when the temperature exceeds the threshold t jsd the transmitter is disabled. th is overtemperature event will be signaled as logical ?low? on the nerr output pin in no rmal-operating mode. after the device has cooled down, the transmitter is re-enabled and ne rr returns to logical ?high?. a hyst eresis is implemented within the temperature sensor. figure 27 overtemperature protection 6.7 rxd recessive clamping detection the rxd recessive clamping detection is only active in normal-operating mode. in normal-operating mode a permanent logical ?high? signal on the rxd pin in dicates the external micr ocontroller, there is no communication on the hs can bus. the microcontroller th en can transmit a message to the can bus, only if the bus is in ?recessive? state. in case the logical ?high? signal on the rxd pin is caused by a a failure, like a short circuit rxd to v io , the rxd signal does not reflect the sign al on the hscan bus. in this case the microcontroller is able to place a message on the ca n bus at any time and corrupts the can messages on the bus. if the TLE9252V detects a logical ?high? sign al on the rxd pin while the bus is dominant for t > t rrc the rxd recessive clamping flag is set alon g with disabling the tran smitter in normal-operating mode. in order to avoid any data collision on the can bu s, the transmitter is disabled in no rmal-operating mode as long as the rxd-recessive clamping is present. in normal-operating mode the TLE9252V indicates the rxd clamping by a logical ?low? signal on the nerr pin. on detection th e transmitter is disabled immediately, so that the corrupted, non-synchronized node is prevented from disturbing the remaining bus traffic. the corrupted node txd t t canh canl rxd t t j t t jsd (shut down temperature) switch-on transmitter a t cool down data sheet 30 rev. 1.01 2018-01-09 TLE9252V high-speed can fd transceiver fail safe functions is then excluded from communication . the TLE9252V releases the failure fl ag and the output stage if the rxd clamping failure disappears . whenever the pin rxd becomes dominant while the bus signal is ?dominant?
