• Dedicated Data Sheets are available for the different product variants

• Complete compatibility (hardware and software) across the family

• TLE9263 with 2 LIN transceivers, 3 voltage regulators

• TLE9262 with 1 LIN transceiver, 3 voltage regulators

Device Description

The TLE9261BQXV33 is a monolithic integrated circuit in an exposed pad VQFN-48 (7mm x 7mm) power

package with Lead Tip Inspection (LTI) feature to support Automatic Optical Inspection (AOI).

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 3.3V low-

dropout 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 3.3V/1.8V 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 undervoltage 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.
