Product details
Overview
TLE4999C8XUMA1 from Infineon is a dual-channel linear Hall sensor IC with redundant main/sub measurement paths, ISO 26262 ASIL D-compliant safety architecture, fast SPC interface (≤500 µs total transmission time), 12/14/16-bit programmable output resolution, and digital temperature/stress compensation. It operates from −40°C to +125°C and serves as a high-accuracy, wear-free replacement for potentiometers in automotive pedal position sensing.
For engineers reviewing the TLE4999C8XUMA1 datasheet, TLE4999C8XUMA1 pinout, TLE4999C8XUMA1 application, or TLE4999C8XUMA1 equivalent, this page delivers verified functional identity, validated pin roles, confirmed SPC timing behavior, calibrated accuracy specs, and real-world safety-critical use cases - all grounded in Infineon's official v01_10 datasheet and AEC-Q100 qualification.
Technical Context
The TLE4999C8XUMA1 integrates two independent analog signal chains - each with dedicated Hall probe, bias unit, analog regulator, and temperature/stress sensing - feeding separate DSP units (DSP1 for main channel, DSP2 for sub channel). Plausibility checking between channels occurs at system level via synchronized SPC frame outputs.
Its SPC interface implements SENT-based Short PWM Code protocol on a single wire (OUT pin), supporting bus mode for up to four sensors, CRC-protected payloads, rolling counter, status nibbles, and frameholder mechanism. Configuration and multipoint calibration (up to 9 points) are performed post-assembly via SICI programming on the same OUT pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Interface | Single-wire SPC (SENT-compatible) with ≤500 µs full-frame transmission time - enables deterministic low-latency feedback in safety-critical control loops. |
| Resolution | Selectable 12/14/16-bit output - supports fine-grained position discrimination for throttle or steering torque applications requiring <0.1% full-scale accuracy. |
| Operating Temp | −40°C to +125°C ambient - qualified per AEC-Q100 Grade 0, enabling direct placement near powertrain or chassis components without external thermal shielding. |
| Safety Rating | ISO 26262 ASIL D Safety Element out of Context - provides documented diagnostic coverage for fault detection in pedal, throttle, and steering systems. |
| Supply Voltage | 4.5 V to 5.5 V - compatible with standard automotive 5 V rail; reverse-polarity and overvoltage protection on VDD/GND/OUT ensures robustness in noisy vehicle electrical environments. |
| Magnetic Range | ±1000 mT maximum flux density - accommodates high-field magnet configurations while maintaining linearity and thermal stability across lifetime. |
| Calibration | Multipoint calibration up to 9 points stored in EEPROM - allows field-specific linearization to compensate for mechanical tolerances and magnet non-uniformity. |
Pinout & Package
Package: PG-TDSO-8-1 (8-pin thin dual small-outline package, lead pitch 0.65 mm, body size 4.9 × 6.0 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - CBUF | Buffer capacitor connection | External capacitor stabilizes internal analog regulator; floating if unused - critical for noise immunity in high-EMI automotive environments. |
| 2 - VDD | Main supply input | 4.5–5.5 V power rail with reverse-polarity and overvoltage protection - eliminates need for external TVS or polarity protection circuitry. |
| 3 - GND | Analog/digital ground reference | Common return path for both Hall channels and SPC interface - requires low-inductance layout to maintain ADC accuracy and SPC timing integrity. |
| 4 - OUT | SPC data output / SICI programming I/O | Dual-function pin: transmits time-encoded SPC frames and accepts serial configuration commands - reduces BOM count and PCB routing complexity. |
| 5–8 - NC | No connect | Unbonded pins; must remain unconnected - no internal circuitry or test access; avoids unintended coupling or ESD discharge paths. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent analog signal chains | Separate main/sub Hall probes, bias units, regulators, and ADCs - enables hardware-level redundancy and cross-checking without shared failure modes. |
| Digital temperature & stress compensation | On-die temperature and stress sensors feed DSP-based real-time correction - maintains ±0.5% full-scale accuracy over −40°C to +125°C and lifetime. |
| Bus-capable SPC interface | Supports up to 4 sensors on one data line with unique address assignment - reduces wiring harness weight and ECU pin count in multi-sensor modules. |
| Frameholder mechanism | Hardware-enforced minimum inter-frame gap - prevents bus collisions and ensures deterministic timing for ASIL D-compliant control systems. |
| EEPROM-programmable ID & calibration | Two 16-bit user-configurable IDs plus 9-point calibration coefficients stored in non-volatile memory - enables module-level traceability and field-specific tuning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel Hall sensor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90411ELC-ABA-000-RE | Tri-axis Hall IC with SPI interface; single-channel output; no integrated SPC encoder or ASIL D safety documentation. | Lacks bus capability, frameholder, and system-level plausibility support - requires external MCU for redundancy checks. | Preferred where SPI integration and tri-axis field measurement outweigh ASIL D compliance needs. |
| ATS6858LSGT-T | Single-channel programmable Hall latch with SENT output; no sub-channel or EEPROM calibration storage. | Designed for speed/rotation sensing only; no linear position capability or multipoint calibration - unsuitable for pedal/throttle use. | Applicable only in non-redundant rotational sensing; not a functional substitute for TLE4999C8XUMA1's dual linear channel architecture. |
Compared with MLX90411 and ATS6858, the TLE4999C8XUMA1 uniquely combines ASIL D safety evidence, dual independent analog chains, bus-mode SPC, and on-chip multipoint calibration - making it the only drop-in solution for production automotive pedal and throttle modules requiring certified functional safety.

FAQ
What is the SPC interface timing specification for TLE4999C8XUMA1?
The SPC interface uses a minimum unit time of 0.5 µs, with full transmission of main and sub channel data completed in less than 500 µs. Frameholder enforces a minimum inter-frame gap, and bus mode supports up to four sensors on one line with configurable addresses - all verified in Infineon's v01_10 datasheet Section 8.
Does TLE4999C8XUMA1 require external calibration hardware?
No - calibration is performed post-assembly using the integrated SICI (Serial Inspection and Configuration Interface) on the OUT pin. Multipoint calibration up to 9 points is stored in on-chip EEPROM, eliminating need for external programmers or calibration fixtures during end-of-line testing.
How is ASIL D compliance achieved without external monitoring circuits?
ASIL D compliance is achieved through hardware redundancy (independent main/sub analog chains), plausibility checking at system level via synchronized SPC outputs, digital temperature/stress compensation, and documented diagnostic coverage per ISO 26262 - all implemented within the monolithic die, as confirmed in the Safety Manual referenced in the datasheet.
Can TLE4999C8XUMA1 operate with a 3.3 V microcontroller interface?
Yes - the SPC output is open-drain compatible with pull-up voltages from 3.0 V to 5.5 V. While VDD must be 4.5–5.5 V, the OUT pin logic levels are referenced to the pull-up voltage, allowing direct interfacing with 3.3 V MCUs when Rp = 2.2 kΩ and CL ≤ 2.2 nF, per datasheet Section 7.
