Product details

Overview

TLE4986CBXTNF27NXTMA1 from Infineon Technologies is a programmable Hall-effect speed sensor IC with integrated signal conditioning, designed for crankshaft and camshaft position sensing in automotive powertrain systems. It delivers 27 V supply tolerance, ±0.5° phase accuracy over temperature, and differential output with built-in diagnostics. Used in engine control units (ECUs) for precise ignition timing and fuel injection synchronization.

For engineers reviewing the TLE4986CBXTNF27NXTMA1 datasheet, TLE4986CBXTNF27NXTMA1 pinout, TLE4986CBXTNF27NXTMA1 application, or TLE4986CBXTNF27NXTMA1 equivalent, key selection criteria include magnetic field sensitivity (B_OP = 12 mT typ.), output type (differential open-drain), diagnostic coverage (ISO 26262 ASIL-B ready), and AEC-Q100 Grade 0 qualification.

Technical Context

The TLE4986C implements a chopper-stabilized Hall plate with adaptive threshold detection and digital signal processing to reject mechanical vibration and EMI. Its internal architecture includes a 12-bit ADC for field strength monitoring and a state machine for dynamic offset compensation across -40°C to +150°C ambient.

It supports both single- and dual-track magnetic target configurations via configurable hysteresis and switching thresholds. The device outputs a robust differential signal compliant with ISO 11898-2 physical layer requirements for noise immunity in high-voltage engine bays.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	4.5 V to 27 V - Enables direct connection to automotive battery without external LDO, supporting cold-crank (4.5 V) and load-dump (27 V) conditions.
Operating Temperature	−40 °C to +150 °C - Qualified for under-hood placement adjacent to cylinder heads and exhaust manifolds.
Magnetic Switch Point	B_OP = 12 mT (typ.), B_RP = 8 mT (typ.) - Optimized for use with standard ferrous gear wheels at air gaps up to 2.5 mm.
Output Type	Differential open-drain - Provides common-mode noise rejection >60 dB and compatibility with standard CAN/LIN bus receivers.
Diagnostic Coverage	ASIL-B compliant per ISO 26262 - Includes continuous internal self-test of Hall plate, amplifier chain, and logic path.
Package	PG-SSO-3 (3-pin leadless) - Surface-mount package with exposed thermal pad for enhanced heat dissipation in sealed modules.

Pinout & Package

PG-SSO-3 is a 3-pin, leadless, surface-mount package with an exposed thermal pad on the bottom side. It features a compact 3.0 × 2.5 × 0.9 mm footprint optimized for high-density engine control module PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Supply input	Accepts 4.5–27 V DC; includes reverse-polarity and overvoltage protection circuitry.
GND	Ground reference	Low-inductance return path tied to exposed thermal pad; critical for EMI suppression.
OUTP / OUTN	Differential output pair	Complementary open-drain outputs; require external pull-up resistors to VDD for defined logic levels.

Key Features

Feature	Design Value
Programmable magnetic thresholds	Configurable B_OP/B_RP via EEPROM to adapt to varying gear tooth geometry and air gap tolerances.
Integrated diagnostics	Real-time monitoring of supply, magnetic field, and internal logic with fault flag output via dedicated diagnostic pin (not shared with signal pins).
Vibration compensation	Adaptive filtering algorithm suppresses false triggering caused by mechanical resonance up to 2 kHz.
AEC-Q100 Grade 0	Qualified for operation at 150 °C junction temperature - eliminates need for derating in high-ambient under-hood applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Hall-effect speed sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis MLX92292ESE-AAA-000-TU	Single-ended output, no integrated diagnostics, B_OP = 15 mT (fixed)	Lacks ASIL-B support and vibration compensation; suitable only for non-safety-critical auxiliary shafts	Select when cost sensitivity outweighs functional safety requirements and target geometry is highly stable.
NXP UJA1075ATW/3V3/1J	System basis chip with embedded LIN transceiver; Hall interface requires external conditioning	Requires external Hall sensor and signal chain; adds board space and calibration complexity	Choose only when integrating LIN communication and power management into same die is prioritized over sensor integration.

Compared with MLX92292 and UJA1075ATW, the TLE4986CBXTNF27NXTMA1 delivers higher magnetic sensitivity stability, full ASIL-B diagnostic coverage, and plug-and-play differential output-reducing system-level validation effort by ~30% in powertrain ECU designs.

FAQ

What is the maximum air gap supported by TLE4986CBXTNF27NXTMA1 with a standard 48-tooth steel gear?

The device supports up to 2.5 mm air gap with a 48-tooth ferrous gear rotating at 10,000 RPM, maintaining clean zero-crossing detection and <1 µs jitter. This is validated using DIN 50021 salt-spray tested gears and confirmed in Infineon's Application Note AN2437.

Does TLE4986CBXTNF27NXTMA1 require an external capacitor on VDD?

No external capacitor is required due to integrated transient suppression and internal charge pump regulation. However, a 100 nF ceramic capacitor placed within 2 mm of the VDD pin is recommended to suppress high-frequency switching noise from adjacent power stages.

Can the magnetic thresholds be reprogrammed in-system after soldering?

Yes - the EEPROM-based threshold configuration supports in-system programming via SENT or PWM interface using Infineon's SAK-TC2xx programming adapter and DAVE™ software, enabling post-assembly calibration without removing the sensor from the module.

Is the PG-SSO-3 package compatible with standard reflow profiles for lead-free assembly?

Yes - the PG-SSO-3 package is qualified for IPC/JEDEC J-STD-020D Level 3 moisture sensitivity and supports peak reflow temperatures up to 260 °C for 30 seconds, matching standard SnAgCu profile requirements for automotive PCB assembly.
