TLE9271QX Description

Short technical summary and product information.

The Infineon TLE9271QX is a high-end System Basis Chip (SBC) designed for automotive applications like body control modules, gateways, and HVAC systems. It features a 750 mA DC/DC buck converter for 5V supply and a 100 mA low-drop voltage regulator, also at 5V, with off-board protection.

Communication interfaces include a high-speed CAN FD transceiver supporting up to 5 Mbps and up to two LIN transceivers compliant with LIN2.2 and SAE J2602. The device also incorporates a configurable watchdog timer and reset output, fail-safe inputs/outputs, and overtemperature/short circuit protection.

Designed for low power consumption in stop and sleep modes, the TLE9271QX can be woken up via bus messages, a dedicated input, or cyclic wake-up. It is housed in a PG-VQFN-48 package and qualified according to AEC-Q100 for automotive use.

Key features include low quiescent current, a DC/DC boost converter for low battery voltage, and software compatibility with other Infineon SBC families. The package is a leadless exposed-pad type with Lead Tip Inspection (LTI) for automated optical inspection.
