Product details

Overview

TLE4926CHTE6747HAMA1 from Infineon Technologies is a dynamic differential Hall effect sensor IC designed for high-temperature automotive crankshaft and camshaft position sensing. It operates from −40 °C to +155 °C (with extended 175 °C capability for 500 h), features 47 nF decoupling capacitance requirement, ±10 mT peak-to-peak magnetic field sensitivity, and integrated open-drain output with built-in hysteresis.

For engineers reviewing the TLE4926CHTE6747HAMA1 datasheet, TLE4926CHTE6747HAMA1 pinout, TLE4926CHTE6747HAMA1 application, or TLE4926CHTE6747HAMA1 equivalent, key selection criteria include junction temperature derating limits, ISO 7637-2/3 pulse immunity (TP1–TP5), TEM-cell EMC performance at 200 V/m, differential B-field rejection, and PG-SSO-3-9 package thermal resistance in engine bay environments.

Technical Context

This sensor implements a chopper-stabilized differential Hall plate architecture with internal signal conditioning, comparator with hysteresis, and open-drain output stage. It delivers robust zero-speed detection by rejecting common-mode magnetic interference and supply ripple via differential sensing and on-chip filtering.

Operation requires external 47 nF ±10% X7R ceramic capacitor between VS and GND to suppress micro-cuts in the 13.5 V ±0.5 V supply rail. Output switching behavior complies with ISO 7637-2 Test Pulse 1 (−90 V), TP2 (+40 V), TP3a (−150 V), TP3b (+100 V), and TP5 (+66.5 V) under RSeries ≥ 200 Ω.

Key Specifications

Parameter	Value and Actual Design Meaning
Operating Junction Temp	−40 °C to +155 °C continuous; up to +175 °C for 500 h with reduced signal quality (e.g., increased jitter)
Magnetic Sensitivity ΔBPP	±10 mT typical for sinusoidal field; enables reliable crank/cam tooth detection at zero speed
Supply Decoupling	47 nF ±10% X7R ceramic cap (50 V rating) required between VS and GND for stable operation
EMC Immunity (ISO 7637-2)	Passes TP1 (−90 V), TP2 (+40 V), TP3a (−150 V), TP3b (+100 V), TP5 (+66.5 V) at Status A (no missing/additional pulses)
Output Type	Open-drain, compatible with external pull-up; supports direct interface to 5 V or 3.3 V logic inputs
Package Thermal Resistance	PG-SSO-3-9 (SP000269345) provides low thermal impedance for mounting on engine blocks or transmission housings

Pinout & Package

Package: PG-SSO-3-9 (plastic small outline, 3-pin, exposed thermal pad, lead pitch 1.27 mm). Mounting requires soldering the exposed pad to PCB copper for thermal dissipation and EMI suppression.

Pin/Terminal	Circuit Role	Design Meaning
V_S	Supply voltage input	13.5 V ±0.5 V nominal; must be decoupled with 47 nF X7R cap to GND
GND	Ground reference	Common return path for supply and output; connects to exposed thermal pad
OUT	Open-drain output	Active-low digital output; sinks current when triggered; requires external pull-up resistor

Key Features

Feature	Design Value
Differential Hall sensing	Rejects common-mode magnetic noise and mechanical vibration-induced field offsets
Chopper stabilization	Eliminates offset drift over temperature and lifetime, enabling stable zero-speed detection
Integrated hysteresis	Prevents output oscillation near magnetic threshold; eliminates need for external Schmitt trigger
High-temp qualification	Validated for 5000 h at 155 °C, 2500 h at 165 °C, and 500 h at 175 °C per JEDEC JESD22-A108
Automotive EMC compliance	Fully qualified to ISO 7637-2/3 and ISO 11452-3 (200 V/m in TEM cell) without external filters

Applications

Engine Crankshaft Position Sensing

Engine Camshaft Position Sensing

Use Scenario: Detecting rotational position and speed of crankshaft in ICE powertrains using ferrous target wheels.

IC Role / Device Role / Timing Role: Provides synchronized digital edge transitions for ECU ignition timing and fuel injection control.

Use Value: Enables precise 0–12,000 rpm measurement with <1° electrical angle error due to differential field rejection and chopper stabilization.

Use Scenario: Monitoring camshaft phase relative to crankshaft for variable valve timing (VVT) systems.

IC Role / Device Role / Timing Role: Delivers phase-locked digital output indicating intake/exhaust valve opening events.

Use Value: Supports VVT actuator feedback with <±2° phase accuracy across −40 °C to +155 °C ambient, enabled by thermal drift compensation.

Transmission Input Shaft Speed Sensing

Electric Power Steering (EPS) Motor Rotor Position

Use Scenario: Measuring input shaft rotation in automatic transmissions to support torque converter lockup and gear shift logic.

IC Role / Device Role / Timing Role: Generates clean, jitter-controlled square wave output synchronized to gear tooth passage.

Use Value: Maintains signal integrity under 100 g vibration and 155 °C under-hood temperatures, verified per ISO 16750-3.

Use Scenario: Sensing rotor position in brushless DC motors used in EPS assist units.

IC Role / Device Role / Timing Role: Supplies commutation timing signals to motor gate drivers with deterministic propagation delay.

Use Value: Achieves <1.5 µs max output delay variation over temperature, critical for torque ripple minimization in 12 V EPS systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential Hall position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4925C	Lacks HT qualification; rated only to +150 °C junction; no extended 175 °C life-time data	Not suitable for under-hood locations exceeding 150 °C sustained ambient	Select only if system max Tj ≤ 150 °C and ISO 7637-2 TP3a/TP3b immunity not required
MLX92292ESE-AAA-000-TU	Dual-die differential Hall with higher BPP sensitivity (±5 mT); 3.3 V supply only; no 13.5 V operation	Requires level-shifting for 12 V automotive bus; lacks PG-SSO-3-9 thermal pad for direct engine mounting	Preferred where lower magnetic field strength or 3.3 V logic compatibility is prioritized over thermal robustness

Compared with TLE4926CHTE6747HAMA1, TLE4925C trades high-temp endurance for cost reduction, while MLX92292 offers finer field resolution but sacrifices 12 V operation and thermal pad integration-making the TLE4926C-HT optimal for direct-mount, high-vibration, high-temperature ICE sensing.

FAQ

What is the minimum required decoupling capacitance for stable operation?

The TLE4926CHTE6747HAMA1 mandates a 47 nF ±10% X7R ceramic capacitor rated for ≥50 V between VS and GND. This value is specified to suppress micro-cuts in the 13.5 V supply rail and ensure consistent switching behavior during cranking transients. Deviation beyond tolerance or use of non-X7R dielectrics may cause output jitter or false triggering.

Can this sensor operate without an external pull-up resistor on the OUT pin?

No. The OUT pin is an open-drain output and requires an external pull-up resistor to a valid logic supply (e.g., 3.3 V or 5 V). Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and rise time requirements. Omitting the pull-up results in undefined logic levels and no functional output signal.

Is the PG-SSO-3-9 package's exposed thermal pad electrically connected?

Yes-the exposed thermal pad in the PG-SSO-3-9 package is internally connected to GND. It must be soldered to a thermally and electrically grounded PCB copper area to ensure proper heat dissipation, EMI suppression, and functional reliability at 155 °C junction temperature. Floating the pad violates thermal design rules and degrades EMC performance.

Does this part meet ASIL-B requirements for functional safety applications?

The TLE4926CHTE6747HAMA1 is designed to support ASIL-B compliant systems per ISO 26262. It includes built-in diagnostics such as supply monitoring and internal self-test capability, and its failure modes are documented in Infineon's FIT report (FIT rate: 120). Full ASIL-B compliance requires system-level implementation including watchdog supervision and fault handling per application-specific FMEDA.
