The TLE9266QX is a monolithic integrated circuit packaged in an exposed pad VQFN-48 (7mm & TImes; 7mm) power supply. The device is designed for a variety of CAN-LIN body applications and can act as a power supply for the microcontroller and as an interface to the CAN and LIN bus networks. To support these applications, the System Basis Chip (SBC) provides many key features such as a 5V Low Dropout Regulator (LDO) for microcontroller power supplies, sensor supply, 5V low dropout regulator with short circuit protection. The HS-CAN transceiver and LIN transceiver for data transfer, the low/high side switch with protection and the 16-bit serial peripheral interface (SPI) for control and monitoring of the device. A window watchdog circuit with reset characteristics, fault output, and undervoltage reset characteristics is also implemented.
The device offers a low power mode to support long-term battery-connected applications. Wake-up from low-power mode can be done via messages on the bus, dual-level sensitive monitoring/wake-up inputs, and cyclic wake-up. The device is designed to withstand the harsh conditions of automotive applications.

SBC Driver Evaluation Board
The SBC drive family is specifically designed for automotive applications such as door, seat control, HVAC and body controllers. These devices contain 1 LIN and / or CAN physical interface.
The SBC Driver Evaluation Board is designed to provide an easy-to-use tool to familiarize yourself with the device and perform application testing. The EV kit includes an SBC driver application board with a 96-pin connector for connection to the Power Easy kit (microcontroller board).
The Power Easy Suite is a test and development platform for use with Infineon devices. The kit uses a 16-bit microcontroller based on the XC2000 processor family of high-performance C166S V2 cores. The Power Easy kit board is designed with a dedicated 96-pin connector for board expansion testing, which is connected to an application board such as an SBC driver.
