TLE9272QXXUMA1 Description

The TLE9272QXXUMA1 is a monolithic integrated circuit in an exposed pad PG-VQFN-48-31 (7mm x 7mm) leadless package with a Lead Tip Inspection (LTI) feature supporting Automatic Optical Inspection (AOI).

The TLE9272QXXUMA1 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 5V supply, another 5V 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.
