OPTIREG™ SBC TLE9274QXV33
Overview
Description
The TLE9274QXV33 is a monolithic integrated circuit in an exposed pad PG-VQFN-48 (7 mm × 7 mm) leadless
package with Lead Tip Inspection (LTI) feature supporting Automatic Optical Inspection (AOI).
The device is designed for various CAN-LIN automotive applications as the main supply for the microcontroller
and as the interface for LIN and CAN bus networks.
The System Basis Chip (SBC) provides the main functions for supporting these applications, such as a Switch
mode power supply regulator (SMPS) for on-board 3.3 V supply, another 5 V low-dropout voltage regulator
with off-board protection, e.g. sensor supply, a DC/DC boost converter for low supply voltage, an HS-
CAN transceiver supporting CAN FD, a LIN transceiver for data transmission and a 16-bit Serial Peripheral
Interface (SPI) to control and monitor the device. Additional feature include a timeout/window watchdog
circuit with a reset feature, fail-safe input and fail-safe outputs and undervoltage reset features.
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 input as well as via cyclic wake.
The device is designed to withstand the severe conditions of automotive applications.
