Infineon TLE9471ESXUMA1, System-On-Chip for Automotive, TSDSO-24

The Infineon TLE9471ESXUMA1 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 (Buck SMPS) 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 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.

Very low quiescent current consumption in Stop- and Sleep Mode
Periodic Cyclic Sense in SBC Normal-, Stop- and Sleep Mode
Low-Drop Buck DC/DC Voltage Regulator 5 V, 500 mA for main supply with integrated spread spectrum modulation feature for optimum EMC performance
Low-Drop Linear Voltage Regulator 5 V, 100 mA, protected features for off-board usage
