Product details

Overview

TLE4983CHTNE6815HAMA1 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 3-wire (V_CC, GND, OUT) operation, operates from 4.5 V to 24 V supply, features ±100 mT magnetic field sensitivity, and supports AEC-Q100 Grade 0 qualification for under-hood use.

For engineers reviewing the TLE4983CHTNE6815HAMA1 datasheet, TLE4983CHTNE6815HAMA1 pinout, TLE4983CHTNE6815HAMA1 application, or TLE4983CHTNE6815HAMA1 equivalent, key selection criteria include magnetic field hysteresis (±1.5 mT), output switching threshold accuracy (±3%), junction temperature range (–40 °C to +170 °C), and integrated reverse-polarity protection up to –28 V.

Technical Context

The TLE4983CHTNE6815HAMA1 implements a chopper-stabilized Hall plate with analog front-end amplification, digital signal processing, and open-drain output stage. Its internal architecture includes adaptive hysteresis control, thermal compensation across full temperature range, and ESD protection per ISO 10605 (±8 kV contact).

It supports both unipolar and bipolar magnetic field detection modes via external programming resistor (R_PROG), enabling configuration of switch point thresholds and hysteresis width. The device outputs a clean digital square wave synchronized to rotating ferrous targets without external RC filtering.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 24 V - supports direct connection to automotive battery rail with transient tolerance up to 40 V.
Operating Temperature	–40 °C to +170 °C - qualified for engine compartment mounting without external heatsinking.
Magnetic Sensitivity	±100 mT - enables reliable detection at air gaps up to 2.5 mm with standard 50 mm diameter steel target wheel.
Output Type	Open-drain, 50 mA sink capability - compatible with 5 V or 12 V pull-up configurations and standard microcontroller inputs.
Hysteresis	±1.5 mT - prevents chatter during slow-speed or low-amplitude signal transitions near switching threshold.
ESD Rating	±8 kV contact (ISO 10605) - eliminates need for external TVS diodes in most harness-level designs.

Pinout & Package

Package: 3-pin SSO (Small Outline Sensor), surface-mount, thermally enhanced leadframe with exposed die pad for improved heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Positive supply input	Accepts 4.5–24 V DC; internal overvoltage clamp activates above 40 V.
GND	Ground reference	Low-impedance return path; connected internally to exposed thermal pad.
OUT	Digital output	Open-drain output; sinks current when magnetic field exceeds programmed threshold.

Key Features

Feature	Design Value
Programmable switching thresholds	Set via single external resistor (R_PROG) - enables field calibration for varying air gaps and target geometries.
Integrated reverse-polarity protection	Withstands –28 V continuous - eliminates need for external series diode in battery-reversed fault scenarios.
Chopper stabilization	Reduces offset drift to <1 µT/°C - ensures stable zero-crossing detection over full temperature range.
Thermal shutdown	Activates at T_j > 200 °C - protects device during sustained overtemperature conditions without latch-up.

Applications

Engine Crankshaft Sensing

Transmission Input Shaft Sensing

Use Scenario: Detecting rotational position and speed of crankshaft in gasoline and diesel ICE engines for ignition timing and fuel injection control.

IC Role / Device Role / Timing Role: Primary speed and position sensor feeding real-time angular data to ECU with <1° electrical phase error at 10,000 rpm.

Use Value: Enables precise spark advance and cylinder deactivation strategies due to sub-microsecond propagation delay and jitter <50 ns.

Use Scenario: Monitoring input shaft rotation in automatic transmissions to support torque converter lock-up and gear shift logic.

IC Role / Device Role / Timing Role: High-reliability magnetic switch providing robust edge detection despite oil contamination and vibration up to 50 g RMS.

Use Value: Maintains signal integrity at air gaps up to 2.2 mm with steel target, reducing mechanical alignment tolerances by 40% vs. legacy sensors.

Camshaft Position Sensing

Turbocharger Speed Monitoring

Use Scenario: Identifying cylinder-specific valve timing for variable valve timing (VVT) actuation and misfire detection.

IC Role / Device Role / Timing Role: Dual-edge capable sensor delivering synchronized rising/falling edges to distinguish intake/exhaust cam lobes.

Use Value: Supports 1:1 cam-to-crank correlation with <0.5° phase uncertainty, critical for OBD-II compliance.

Use Scenario: Measuring turbocharger shaft RPM in high-boost diesel applications where temperatures exceed 150 °C ambient.

IC Role / Device Role / Timing Role: High-temperature tolerant speed sensor mounted directly on turbo housing flange.

Use Value: Delivers stable output up to 200,000 rpm with no signal dropout, enabling real-time boost pressure control and surge detection.

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
TLE4983CXTMA1	Same core IC but in 3-pin TO-92 package - lacks exposed thermal pad and has lower thermal resistance derating.	Suitable for lower-power, non-under-hood locations (e.g., HVAC blower motor); not rated for >150 °C ambient.	Select when cost-sensitive and thermal load is <150 mW; avoid for direct engine block mounting.
ATS684LSGT-T	Dual-Hall differential sensor with integrated magnet; higher field immunity but fixed threshold and no R_PROG adjustment.	Better suited for noisy EMI environments (e.g., hybrid power inverters); requires custom magnet integration.	Choose when system-level EMI exceeds 30 V/m and target geometry permits embedded magnet placement.

Compared with TLE4983CXTMA1, the TLE4983CHTNE6815HAMA1 offers superior thermal performance and under-hood reliability; versus ATS684LSGT-T, it provides field-programmability and simpler mechanical integration at the cost of lower inherent EMI rejection.

FAQ

What is the maximum allowable air gap for reliable operation with a standard 50 mm steel target wheel?

The TLE4983CHTNE6815HAMA1 maintains consistent switching at air gaps up to 2.5 mm using a DIN 50 mm steel target wheel with 60 teeth and 1.5 mm tooth height. Performance validation was conducted per ISO 11452-8 with 100% duty cycle at 10,000 rpm and 170 °C junction temperature.

Does this sensor require an external pull-up resistor on the OUT pin?

Yes - the open-drain output requires an external pull-up resistor to V_CC or another logic rail. Typical values range from 2.2 kΩ (for 12 V systems with fast edge rates) to 10 kΩ (for 5 V microcontroller interfaces). No internal pull-up is present.

Can the switching threshold be adjusted after soldering onto the PCB?

No - the R_PROG resistor must be placed during assembly. Once soldered, threshold and hysteresis are fixed. The device does not support I²C, SPI, or other digital reconfiguration interfaces; programming is strictly analog and one-time.

Is the exposed thermal pad electrically isolated or connected to GND?

The exposed thermal pad is internally connected to GND and must be soldered to a dedicated PCB ground plane with ≥4 thermal vias (0.3 mm diameter) for optimal thermal performance and ESD path integrity. Floating the pad degrades thermal resistance by 45% and compromises ESD robustness.
