Product details
Overview
TLE9461ESV33XUMA1 from Infineon is a monolithic System Basis Chip (SBC) for automotive CAN FD networks, integrating a 3.3 V/150 mA LDO main regulator, 5 V/100 mA protected auxiliary regulator, HS-CAN FD transceiver (up to 5 Mbit/s), configurable HV GPIO, and SPI interface - deployed in HVAC ECUs, seat control modules, and smart power distribution units.
For engineers reviewing the TLE9461ESV33XUMA1 datasheet, TLE9461ESV33XUMA1 pinout, TLE9461ESV33XUMA1 application, or TLE9461ESV33XUMA1 equivalent, key selection criteria include CAN FD compliance (ISO 11898-2:2016), dual-LDO output capability with off-board protection, cyclic wake/sense functionality in Stop/Sleep modes, and AEC-Q100 qualification for permanent-battery automotive systems.
Technical Context
The device implements a multi-state SBC state machine (Normal, Stop, Sleep, Fail-Safe, Development) with configurable timeout/window watchdog, undervoltage reset, and dedicated TEST pin for development mode entry. Wake-up sources include CAN message, bi-level HV wake input, and periodic Cyclic Wake with programmable interval.
Its integrated HS-CAN FD transceiver supports CAN Off, Normal, Receive-Only, and Wake Capable modes with bus dominant clamping, TXD time-out, and undervoltage detection. The charge pump output enables N-channel MOSFET reverse-polarity protection with spread-spectrum modulation for EMC optimization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CAN Data Rate | Up to 5 Mbit/s - enables high-bandwidth CAN FD communication per ISO 11898-2:2016 and SAE J2284. |
| Main Regulator Output | 3.3 V / 150 mA (250 mA peak) - powers microcontrollers directly with low-dropout operation across battery voltage range. |
| Auxiliary Regulator Output | 5 V / 100 mA with short-to-battery protection - supplies off-board sensors safely without external protection circuitry. |
| Quiescent Current (Sleep Mode) | ≤ 20 µA - minimizes battery drain in always-on automotive modules requiring long-term standby. |
| Operating Voltage Range | 4.5 V to 28 V - supports full automotive battery range including cold-crank and load-dump conditions. |
| Temperature Range | −40 °C to +150 °C - qualified for under-hood and ECU interior placement per AEC-Q100 Grade 0. |
| SPI Interface | 16-bit serial peripheral interface - enables full configuration, status monitoring, and fault reporting to host MCU. |

| WK | High-voltage wake input | Bi-level sensitive input (1.5 V / 7 V thresholds) for wake-up via external switch or voltage monitoring. |
| FO/GPIO | Fail output / configurable HV I/O | Programmable as fail-safe signal, wake source, low/high-side switch, or HV measurement input. |
| TEST | Development mode entry | Pull-low to enter SBC Development Mode: stops watchdog, enables debug access via SPI. |
| CSN / SCLK / MOSI / MISO | SPI interface signals | Full-duplex 16-bit SPI for register read/write, status polling, and configuration of all SBC functions. |
Key Features
| Feature | Design Value |
|---|---|
| Cyclic Wake & Sense | Configurable periodic wake-up and sensing in Normal/Stop/Sleep modes - eliminates need for external RTC or timer IC. |
| Spread Spectrum Modulation | Integrated on-chip modulation for charge pump output - reduces peak EMI by >10 dB without external filtering components. |
| Reverse Polarity Protection | Charge pump drives external N-MOSFET - enables cost-effective, low-RDS(on) reverse-battery protection vs. P-MOSFET solutions. |
| HV Measurement Interface | Reconfigurable FO/GPIO pin supports ratiometric voltage sensing up to 60 V - replaces discrete resistor dividers in battery monitoring. |
| Software Compatibility | Register map and SPI command set aligned with TLE926x/TLE927x families - enables scalable software reuse across Infineon SBC platforms. |
Applications
| HVAC ECU Power & Communication | Seat Control Module |
|---|---|
|
Use Scenario: Central HVAC controller powered continuously from vehicle battery, communicating via CAN FD to climate sensors and actuators. IC Role / Device Role / Timing Role: Main system power source (3.3 V MCU supply + 5 V sensor rail), CAN FD transceiver, and wake controller for sleep/wake transitions. Use Value: Ultra-low 20 µA sleep current extends battery life during vehicle off-state; cyclic wake enables timed cabin pre-conditioning without external timers. |

IC Role / Device Role / Timing Role: Integrated power management, CAN FD interface, and configurable FO/GPIO for heater relay control and fault indication. Use Value: Single-chip solution eliminates discrete LDOs, CAN transceiver, and protection FETs - reduces BOM count by ≥7 components and PCB area by 35%. |
| Smart Power Distribution Unit | Steering Column Control |
|
Use Scenario: Zone-based power node managing switched 12 V outputs to lighting, pumps, and comfort modules using CAN FD commands. IC Role / Device Role / Timing Role: High-voltage GPIO used as configurable high-side switch; 5 V regulator powers local CAN transceivers; CAN FD handles command routing. Use Value: HV GPIO supports 60 V measurement and 500 mA switching - enables direct integration of load monitoring and control without external sense amps or drivers. |
Use Scenario: Steering column ECU managing electric power assist, lock/unlock, and tilt/telescope functions with safety-critical timing. IC Role / Device Role / Timing Role: Fail Output (FO) provides hardware-level fault signaling to body domain controller; watchdog ensures deterministic reset on firmware hang. Use Value: Dedicated fail-safe output meets ASIL-B functional safety requirements for steering-related ECUs without additional safety monitor IC. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE9461ES50XUMA1 | 5 V main regulator (150 mA), no 3.3 V output - same package, pinout, and SPI interface. | Targets 5 V MCU platforms (e.g., legacy 8-bit automotive MCUs); lacks native 3.3 V supply for modern Cortex-M cores. | Select when primary MCU requires 5 V supply and external 3.3 V regulation is already present. |
| TLE9471ESV33XUMA1 | Includes LIN transceiver + enhanced watchdog (window + timeout), same 3.3 V/150 mA regulator and CAN FD. | Supports dual-bus (CAN + LIN) nodes like door modules; adds LIN physical layer and extended diagnostics. | Choose for mixed-protocol ECUs needing both CAN FD and LIN 2.2A, where footprint and software compatibility are critical. |
Compared with TLE9461ESV33XUMA1, the TLE9461ES50XUMA1 shifts regulator output to 5 V for legacy MCU support, while TLE9471ESV33XUMA1 adds LIN capability and advanced watchdog features - both retain identical CAN FD performance, package, and software stack for seamless migration.

FAQ
What is the maximum CAN FD data rate supported by TLE9461ESV33XUMA1?
The device supports HS-CAN FD up to 5 Mbit/s, fully compliant with ISO 11898-2:2016 and SAE J2284-4. This enables high-throughput firmware updates and real-time sensor streaming in modern automotive networks without requiring external CAN controllers or transceivers.
Does TLE9461ESV33XUMA1 include built-in protection against reverse battery connection?
Yes - it integrates a charge pump output that drives an external N-channel MOSFET for reverse-polarity protection. This architecture achieves lower conduction losses than P-MOSFET solutions and includes spread-spectrum modulation to minimize EMI during switching.
Can the 5 V auxiliary regulator power external sensors directly?
Yes - the V5OUT pin delivers 5 V at 100 mA with integrated short-to-battery protection. It is designed for off-board sensor supply, eliminating the need for external overvoltage or reverse-current protection components in typical automotive sensor interfaces.
Is TLE9461ESV33XUMA1 pin-compatible with other devices in the TLE94xx family?
Yes - all TLE94xx variants, including TLE9461ESV33XUMA1, use the identical PG-TSDSO-24-1 package with exposed pad and share identical pin assignment. Hardware design reuse is enabled across 3.3 V and 5 V regulator versions, CAN-only and CAN+LIN variants.
