Device Description
The TLE9262BQXV33 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
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
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.
