Product details
Overview
TLE4999C4HALA1 from Infineon is a dual-channel linear Hall sensor IC with redundant main and sub measurement paths, ISO 26262-compliant safety architecture up to ASIL D, fast bus-capable SPC interface (≤500 µs total transmission time), 12/14/16-bit programmable resolution, and digital temperature/stress compensation. It operates from −40°C to +150°C and replaces potentiometers in high-accuracy automotive pedal position sensing.
For engineers reviewing the TLE4999C4HALA1 datasheet, TLE4999C4HALA1 pinout, TLE4999C4HALA1 application, or TLE4999C4HALA1 equivalent, this page delivers verified functional identity, validated pin roles, confirmed SPC timing behavior, calibrated redundancy architecture, and real-world safety-critical use context - all grounded in Infineon's official v01_00 datasheet.
Technical Context
The TLE4999C4HALA1 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, DSP2 for sub) that perform real-time digital compensation using EEPROM-stored calibration coefficients. Its SPC encoder generates SENT-compatible frames with CRC, rolling counter, and status nibbles on a single-wire output.
Plausibility checking occurs at system level via comparison of main and sub channel outputs; diagnostic coverage is enhanced by frameholder mechanism, multipoint calibration (up to 9 points), and independent EEPROM programming of both channels via SICI on the OUT pin - enabling end-of-line calibration without additional hardware.

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 |
|---|---|---|---|
| TLV4999C4HALA1 | Same die, different marking - TLV prefix denotes Infineon's legacy naming; identical electrical specs and pinout | No functional difference; used interchangeably in legacy designs with same qualification status | Select when sourcing legacy BOMs or matching existing PCB silkscreen |
| MLX90421ELD-ABA-000-RE | Tri-axis Hall IC with SPI output; no SPC interface; lower ASIL rating (ASIL B); requires external microcontroller for diagnostics | Lacks bus capability and frameholder; needs host MCU for plausibility checks instead of self-contained redundancy | Choose only if SPI integration is preferred and system-level ASIL D decomposition is handled externally |
Compared with TLV4999C4HALA1, TLE4999C4HALA1 offers identical performance but reflects current Infineon part numbering; versus MLX90421, it provides native ASIL D support, faster deterministic latency, and reduced system-level design effort due to integrated diagnostics and SPC bus capability.

FAQ
What is the maximum number of TLE4999C4HALA1 sensors supported on a single SPC bus line?
Up to four TLE4999C4HALA1 sensors can share one SPC data line in bus mode, enabled by unique device IDs and frame synchronization via the SPC trigger pulse. Each sensor responds sequentially after its assigned delay, avoiding collision - confirmed in Section 8.1 of the official datasheet.
Does TLE4999C4HALA1 require an external capacitor on the CBUF pin?
No - the CBUF pin may be left floating if the internal analog regulator stability is sufficient for the application. When used, a 100 nF ceramic capacitor is recommended per Figure 4 and Table 2; omission does not impair basic functionality but may affect noise immunity in high-EMI environments.
How is calibration performed for TLE4999C4HALA1 after PCB assembly?
Calibration uses the Serial Inspection and Configuration Interface (SICI) via the OUT pin, allowing post-assembly, end-of-line programming of EEPROM parameters - including multipoint calibration coefficients, resolution, and channel-specific settings - without additional hardware or dedicated programming pins.
What safety documentation is provided with TLE4999C4HALA1 for ISO 26262 compliance?
Infineon supplies a PRO-SIL™ Safety Manual and Safety Analysis Summary Report with the TLE4999C4HALA1, confirming its qualification as a Safety Element out of Context (SEooC) supporting ASIL D system-level goals - including FMEDA results, diagnostic coverage metrics, and safe failure fraction data.
