TLE9263QX System Basis Chip with 5V LDO, CAN FD Transceiver, 2 LIN Interfaces and 4 High-Side Outputs - VQFN-48 Package

This device is a highly integrated System Basis Chip (SBC) designed for a wide range of CAN-LIN automotive electronic control unit applications.
It serves as the main power supply for the microcontroller while providing robust interface capabilities for CAN and LIN bus networks in vehicles .
The chip integrates a 5V low-dropout voltage regulator capable of delivering up to 250mA, making it ideal for powering the primary microcontroller.
A second 5V LDO offers 100mA output with off-board protection features for supplying external sensors, ensuring reliable power delivery to peripheral components .
The integrated high-speed CAN transceiver fully supports the CAN FD protocol, enabling data transmission speeds of up to 2 Mbps for advanced communication needs .
Two LIN transceivers compliant with LIN 2.2 and J2602 standards provide additional connectivity for body electronics and peripheral modules .
Four integrated high-side outputs with 7-ohm typical on-resistance allow direct control of small loads such as LEDs or relays without external drivers .
A 16-bit SPI interface enables comprehensive device configuration, real-time monitoring, and diagnostics for system control .
The device features configurable timeout and window watchdog circuits with reset functionality, ensuring safe operation and system reliability .
Multiple low-power modes, including Stop and Sleep modes, minimize current consumption for applications permanently connected to the battery .
Wake-up from low-power modes can be triggered via bus messages, dedicated wake inputs, or cyclic wake events .
The chip is housed in a space-saving VQFN-48 (7mm x 7mm) package with an exposed pad and supports automatic optical inspection (AOI) for manufacturing ease .
This component is fully AEC-Q100 qualified and operates reliably across a wide temperature range, making it suitable for demanding automotive environments .
