TLE9263BQX System Basis Chip with 5V LDO, CAN FD Transceiver, LIN Interfaces and 4 High-Side Outputs - VQFN-48 Package

This device is a highly integrated System Basis Chip (SBC) designed specifically for demanding automotive electronic control unit (ECU) applications.
It serves as the main power supply for microcontrollers 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 protected 5V LDO offers 100mA output for off-board sensors, ensuring reliable power delivery to external components.
The integrated high-speed CAN transceiver fully supports the CAN FD protocol, enabling data transmission speeds of up to 5 Mbps for advanced communication needs.
Two LIN transceivers compliant with LIN 2.2a 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 package with an exposed pad and supports automatic optical inspection (AOI) for manufacturing ease.
This component is fully qualified for automotive applications and operates reliably across a wide temperature range from -40°C to 150°C.
