Description
The TLE9461-3ES is a monolithically integrated circuit in an exposed pad PG-TSDSO-24-1 (150 mil) power package. 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 5 V lowdropout voltage regulator (LDO) for e.g. a microcontroller supply, another 5 V low-dropout voltage regulator with off-board protection for e.g. sensor supply, a HS-CAN transceiver supporting CAN FD and CAN Partial Networking (incl. FD tolerant mode) for data transmission, a high-voltage GPIO with embedded protective functions and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device. Also a configurable timeout / window watchdog circuit with a reset feature, one dedicated fail output and an undervoltage reset feature are implemented.
The device offers low-power modes in order to minimize current consumption in applications that are connected permanently to the battery. A wake-up from the low-power mode is possible via a message on the CAN bus, via the bi-level sensitive monitoring/wake-up input as well as via Cyclic Wake.
The device is designed to withstand the severe conditions of automotive applications
