TLE9261QX | The TLE9261QX is a monolithic integrated circuit in an exposed pad VQFN-48 (7mm x 7mm) power package with LTI feature to support AOI

Overview

The device is designed for various CAN automotive applications as main supply for the microcontroller and as interface for a CAN bus network.

To support these applications, the System Basis Chip (SBC) provides the main functions, such as a 5V lowdropout voltage regulator (LDO) for e.g. a microcontroller supply, another 5V low-dropout voltage regulator with off-board protection for e.g. sensor supply, another 5V/3.3V regulator to drive an external PNP transistor, which can be used as an independent supply for off-board usage or in load sharing configuration with the main regulator VCC1, a HS-CAN transceiver supporting CAN FD for data transmission, high-side switches with embedded protective functions and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device. Also implemented are a configurable timeout / window watchdog circuit with a reset feature, three Fail Outputs and an under voltage reset feature.

The device offers low-power modes in order to minimize current consumption on applications that are connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the buses, via the bi-level sensitive monitoring/wake-up inputs as well as via cyclic wake. The device is designed to withstand the severe conditions of automotive applications.
