TLE9261-3BQX Description

Short technical summary and product information.

The Infineon TLE9261-3BQX is a versatile System Basis Chip (SBC) designed for automotive body control modules, gateway applications, and other specialized systems. It features two integrated low-drop voltage regulators: a main regulator capable of 5V up to 250 mA (with a 3.3V variant available) and an auxiliary regulator providing 5V up to 100 mA with off-board usage protection.

This SBC includes a high-speed CAN transceiver that supports CAN FD communication up to 5 Mbit/s, featuring CAN Partial Networking and a CAN FD tolerant mode compliant with ISO 11898-2:2016 and SAE J2284 standards. It also offers four high-side outputs with a typical resistance of 7 Ω, two High-Voltage GPIOs, and three High-Voltage wake inputs.

Integrated fail-safe and supervision functions, such as a watchdog timer and interrupt/reset outputs, enhance system reliability. Configuration and diagnostics are managed via a 16-bit SPI interface. The TLE9261-3BQX is qualified for automotive applications according to AEC-Q100 standards and comes in a PG-VQFN-48 package.

Potential applications include Body Control Modules (BMC), passive keyless entry and start modules, gateway applications, HVAC systems, seat and closure modules, and light control modules.
