TLE9274QX

The device is designed for various CAN-LIN automotive applications as the main supply forthe microcontroller and as the Interface for LIN and CAN bus networks.

The System Basis Chip (SBC) provides the main functions for supporting these applications, such as a Switch Mode Power Supply regulator (SMPS) for on-board 5V supply, another 5V low-dropout voltage regulator with off-board protection, e.g. sensor supply, a DC/DC Boost converter for low supply voltage, an HS-CAN transceiver supporting CAN FD, a LIN transceiver for data transmission and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device. Additional feature include a timeout / window watchdog circuit with a reset feature, Fail-Safe Input and Fail-Safe Outputs and undervoltage reset features.
The device offers low-power modes in order to minimize current consumption on applications that are connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the buses, via the bi-level sensitive mon itoring/wake-u p input as well as via cyclic wake.
The device is designed to withstand the severe conditions of automotive applications.
