Device Description
The TLE9263QX 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-LIN automotive applications as main supply for the microcontroller and_as interface for a LIN and_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 and_LIN transceiver 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.
