TLE9261BQXXUMA1

Specialized Overview

The TLE9261BQXXUMA1 is a monolithic automotive System Basis Chip (SBC) in a PG-VQFN-48 package. It integrates two low-dropout voltage regulators: a main regulator delivering up to 250 mA at 5 V or 3.3 V, and an auxiliary regulator providing up to 100 mA at 5 V with off-board protection. A third configurable regulator supports external PNP transistors for load sharing. The device includes a high-speed CAN transceiver supporting FD communication up to 5 Mbit/s per ISO 11898-2:2016. Power management features include four high-side switches, two HV GPIOs, three wake inputs, and comprehensive supervision functions such as watchdogs and thermal shutdown.
