TLE9250SJXUMA1

TLE9250SJXUMA1 is a driver/receiver, transceiver and transponder for LIN 2.x, J2602 and ISO9141 physical layer. It includes a capacitively-coupled transmitter and receiver, a LIN transceiver and transponder, as well as analog and digital functions for operating the physical layer. The TLE9250SJXUMA1 is ideally suited for applications such as diagnostic systems and Remote Keyless Entry (RKE) systems.

The TLE9250SJXUMA1\'s transmitter and receiver circuit is suitable for automotive applications where capacitively-coupled signals are used for communication. The TLE9250SJXUMA1 has both a transmitter and a receiver that use solid-state switches to enable coupling of the voltage signal to the twisted-pair LIN bus. The transmitter and receiver circuits both have a high level of signal isolation, which is necessary for reliable operation in noisy automotive electrical environments.

The TLE9250SJXUMA1 transceiver supports LIN communication at 2.5 Mbps, 5 Mbps, 10 Mbps, and 20 Mbps. It also supports the J2602 physical layer standard and ISO9141 communication. The transceiver provides high-speed communications, operating up to 20 Mbps. The receiver input has an internal pullup resistor to provide a logical high signal input to the internal bus. The transmitter output has an open-collector structure to allow data to be sent to the bus without worrying about a permanent connection.

The TLE9250SJXUMA1 also includes a LIN transponder for receiving data from the bus and to transmit data to the bus. The transponder consists of a bidirectional control register and a programmable memory unit. The control register is used to program the various parameters in the LIN transponder, such as baud rate, node address, bus activity monitor, etc. The programmable memory unit can be used to save data for use in an application, such as in fleet management or automotive diagnostics.

The TLE9250SJXUMA1 also has several analog and digital functions designed for automotive communication applications. The analog part of the TLE9250SJXUMA1 includes a comparator, a comparator latch, a power-on reset and surge protection and a programmable negative voltage, while the digital part includes a programmable pullup/pulldown resistor and a programmable frequency divider. All these features make the TLE9250SJXUMA1 ideal for use in automotive applications that require reliable communications.

In conclusion, the TLE9250SJXUMA1 is a driver/receiver, transceiver and transponder for LIN 2.x, J2602 and ISO9141 physical layer. Its transmitter and receiver are suitable for capacitively-coupled automotive applications and its transceiver supports a wide range of data rates. The transponder allows for bidirectional communication with the LIN bus. Its analog and digital functions make it suitable for automotive communication applications.
