Product Details
TLE9471ESXUMA1 - OPTIREG Lite Buck CAN System Basis Chip
TLE9471ESXUMA1 from Infineon Technologies is an automotive CAN FD system-basis chip with a 5 V buck regulator, protected auxiliary LDO, watchdog and high-voltage I/O in a 24-lead exposed-pad TSDSO package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
TLE9471ES integrates a 5 V buck main supply, protected 5 V/100 mA auxiliary supply, high-speed CAN FD transceiver, wake inputs, watchdog, reset and SPI diagnostics.
Key Advantages
Combines an efficient buck MCU supply with CAN FD networking and low-power wake management.
Adds configurable watchdog, reset, fail output and high-voltage GPIO supervision in one automotive-qualified SBC.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Automotive CAN FD system basis chip
CAN FD up to 5 Mbit/s and 16-bit SPI control
Automotive supply environment; -40 C to +150 C junction range per data sheet
24-TSSOP (0.154", 3.90mm Width) Exposed Pad
Package & Footprint
This ordering code uses the 24-TSSOP (0.154", 3.90mm Width) Exposed Pad package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.

Replacement Considerations
No exact TLE9471ES alternative was found in the local database. TLE9461ES uses an LDO rather than the same buck supply architecture.
Manufacturer Information
Infineon marks TLE9471ESXUMA1 active and preferred. Validate buck components, EMC, CAN and thermal behavior to the dedicated data sheet.
Applications
Supplies the MCU efficiently while providing CAN FD and wake supervision.
Supports battery-connected modules with low-power states and protected sensor supply.
Quality & Authenticity
Match the complete ordering code, package marking and reel or lot label to authorized-channel records. Inspect moisture handling and solderability requirements before assembly.
