TLE9278BQX Description

Short technical summary and product information.

The Infineon TLE9278BQX is a highly integrated System Basis Chip designed for automotive applications requiring multiple CAN transceivers, such as gateways and advanced Body Control Modules. It features a 3.3V output SMPS buck regulator capable of delivering up to 750mA, alongside a DC/DC boost converter for low supply voltage conditions.

 

This device supports four CAN transceivers compliant with CAN Flexible Data-rate (FD) and ISO 11898-2:2016 standards, operating up to 5 Mb/s. Control and monitoring are managed via a 16-bit Serial Peripheral Interface (SPI). Additional features include overtemperature and short-circuit protection, a reset output, and fail output.

 

The TLE9278BQX is designed for low-power modes to support battery-connected applications, with wake-up capabilities via bus messages, a dedicated wake-up input, or an integrated timer. It is supplied in a compact 7x7mm PG-VQFN-48 package suitable for surface mounting.

 

Qualified for automotive applications according to AEC-Q100/101, this chip offers a wide input voltage and temperature range, making it a robust solution for demanding automotive environments.
