描述 Description

The TLE9263-3BQX V33 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 3.3V 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 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 CAN Partial Networking (incl. FD tolerant mode) and LIN transceiver for data transmission, high-side switches with embedded protectivefunctions 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.
