Product details
Overview
TLE94713ESXUMA1 from Infineon Technologies is a monolithic System Basis Chip (SBC) integrating a 5 V/500 mA buck DC/DC regulator, 5 V/100 mA LDO, high-speed CAN FD transceiver (up to 5 Mbit/s), configurable HV GPIO, charge pump output for reverse-polarity protection, and SPI interface - all in PG-TSDSO-24-1 EP package. It serves as main power supply and CAN interface for automotive ECUs such as HVAC controllers, light control units, and exhaust modules.
For engineers reviewing the TLE94713ESXUMA1 datasheet, TLE94713ESXUMA1 pinout, TLE94713ESXUMA1 application, or TLE94713ESXUMA1 equivalent, key selection criteria include CAN FD partial networking support, cyclic wake/sense capability in Stop/Sleep modes, spread spectrum modulation for EMC optimization, and AEC-Q100 qualification for permanent battery-connected automotive systems.
Technical Context
The device implements a multi-state SBC state machine with Normal, Stop, Sleep, Restart, Fail-Safe, and Development modes - each supporting periodic Cyclic Wake and Cyclic Sense functions for low-power system monitoring. Its CAN transceiver complies fully with ISO 11898-2:2016 and SAE J2284, enabling CAN FD communication and Partial Networking with FD-tolerant mode.
The integrated 5 V buck regulator uses spread spectrum modulation to reduce EMI peaks, while the secondary 5 V LDO includes off-board protection features. The HV GPIO supports fail-safe signaling, wake input, high-/low-side switching, or voltage measurement - all configurable via SPI register writes without hardware rework.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Input Range | 4.5 V to 40 V - supports cold-crank and load-dump conditions in 12 V automotive systems. |
| Buck Regulator Output | 5 V ±2%, 500 mA - powers microcontrollers and core logic with integrated spread spectrum for EMC compliance. |
| LDO Output | 5 V ±2%, 100 mA - supplies sensors or peripherals with overcurrent and thermal protection. |
| CAN Data Rate | Up to 5 Mbit/s - enables CAN FD frame transmission and reception with partial networking support. |
| Quiescent Current (Sleep) | ≤ 20 µA - minimizes battery drain during extended vehicle-off periods. |
| Operating Temperature | −40 °C to +150 °C - qualified for under-hood and cabin ECU placement per AEC-Q100 Grade 0. |
| SPI Interface | 16-bit, full-duplex - enables real-time configuration of watchdog, wake sources, GPIO modes, and diagnostics flags. |

Key Features
| Feature | Design Value |
|---|---|
| Cyclic Wake in Sleep/Stop Mode | Enables periodic self-wake every 1–65535 ms without CAN traffic or external trigger - reduces system standby power. |
| CAN Partial Networking Support | Allows selective node wake-up via targeted WUP/WUF frames - eliminates unnecessary bus activity in multi-ECU networks. |
| Spread Spectrum Modulation (Buck & CP) | Reduces peak radiated emissions by >10 dB across 150 kHz–108 MHz band - simplifies EMC filter design. |
| Configurable Timeout/Window Watchdog | Independent 16-bit timer with windowed operation - prevents runaway code while tolerating deterministic delays. |
| HV Measurement Function | Reuses GPIO pin to measure external voltages up to 28 V with 10-bit resolution - eliminates need for external ADC. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar System Basis Chip applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE94712ESXUMA1 | Same pinout and SPI register map, but lacks CAN FD support (HS-CAN only up to 1 Mbit/s). | Suitable for legacy CAN 2.0B networks without bandwidth or data-length upgrade needs. | Select when CAN FD is not required and cost sensitivity favors simpler transceiver. |
| TLE9263QXXUMA1 | Different package (PG-DSO-36), no spread spectrum modulation, lower max input voltage (28 V), and no Cyclic Sense feature. | Targeted at non-FD, lower-voltage chassis modules where EMC headroom is less constrained. | Choose for higher pin count needs and compatibility with TLE926x software stack, but verify thermal derating at 40 V. |
Compared with TLE94712ESXUMA1 and TLE9263QXXUMA1, the TLE94713ESXUMA1 uniquely delivers CAN FD + Partial Networking + Cyclic Sense in a compact 24-pin package with best-in-class 20 µA sleep current and dual spread spectrum domains - making it optimal for next-gen low-power, high-bandwidth automotive nodes.

FAQ
Does TLE94713ESXUMA1 support CAN FD Classic arbitration?
Yes, the device operates in CAN FD tolerant mode per ISO 11898-2:2016, allowing seamless coexistence with CAN 2.0B nodes on the same bus while supporting FD data phases when communicating with FD-capable peers. Arbitration fields remain compatible with classical CAN bit timing.
What is the maximum allowable VBAT transient for TLE94713ESXUMA1?
The device withstands load dump transients up to 40 V for 400 ms per ISO 7637-2 Pulse 5a, and cold-crank down to 4.5 V. Absolute maximum VBAT rating is 45 V, but sustained operation above 40 V is not guaranteed and may trigger overvoltage protection.
Can the HV GPIO be used simultaneously as wake input and fail output?
No - the GPIO pin is functionally multiplexed; its mode (wake input, fail output, high-side switch, etc.) is selected via SPI configuration registers and cannot operate in two roles concurrently. Reconfiguration requires SPI write and mode transition sequence.
Is spread spectrum modulation enabled by default on power-up?
Yes, spread spectrum modulation is active on both the buck regulator and charge pump outputs immediately after reset. It can be disabled via SPI register bit SSM_DIS (address 0x1E, bit 0), but disabling is not recommended unless EMI testing confirms compliance without it.
