Device Description
The TLE9262-3BQX 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 including the CAN Partial Networking feature.
To support these applications, the System Basis Chip (SBC) provides the main functions, such as a 5V 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 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 CAN Partial Networking (incl. FD tolerant
mode)
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 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.
