Product details

Overview

TLE4983CHTNE6747HAMA1 from Infineon Technologies is a monolithic Hall-effect speed sensor IC with integrated signal conditioning, designed for crankshaft and camshaft position sensing in automotive powertrain systems. It delivers differential output (A/B), operates from 4.5 V to 24 V supply, features built-in reverse-polarity protection, and supports junction temperatures up to +150 °C.

For engineers reviewing the TLE4983CHTNE6747HAMA1 datasheet, TLE4983CHTNE6747HAMA1 pinout, TLE4983CHTNE6747HAMA1 application, or TLE4983CHTNE6747HAMA1 equivalent, key selection criteria include differential output compatibility with ECU input stages, robust EMC performance per ISO 11452-2/4, and programmable hysteresis for gear tooth edge detection under high-vibration conditions.

Technical Context

The TLE4983CHTNE6747HAMA1 implements a bipolar Hall latch with chopper-stabilized amplifier and differential comparator architecture. Its internal voltage regulator enables operation across wide battery voltage ranges, and the integrated EEPROM stores calibration data for magnetic offset compensation.

It uses a 3-pin SSO (Small Outline Sensor) package with exposed thermal pad, and its output stage is configured as open-drain push-pull differential pair - supporting both single-ended and differential interface modes depending on external pull-up configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 24 V - Enables direct connection to automotive battery without external LDO.
Output Type	Differential open-drain A/B - Allows noise-immune signal transmission over long harness runs.
Junction Temp	−40 °C to +150 °C - Qualified for under-hood engine compartment mounting.
Magnetic Sensitivity	B_OP = ±15 mT typical - Matches standard ferrous gear tooth targets at air gaps up to 2.5 mm.
EMC Immunity	ISO 11452-2 (200 V/m) & ISO 11452-4 (150 mA) - Meets OEM-level radiated and bulk current injection requirements.
Response Time	≤ 3 µs - Supports crankshaft sensing up to 20,000 RPM at 60-tooth wheel.

Pinout & Package

Package: 3-pin SSO (Small Outline Sensor) with exposed thermal pad (HTSSOP variant), footprint compatible with PCB reflow soldering and mechanical mounting via integrated clip.

Pin/Terminal	Circuit Role	Design Meaning

Key Features

Feature	Design Value

Dual-output differential mode	Provides A/B outputs with phase shift matching ECU timing requirements for direction detection.

Applications

Engine Crankshaft Sensing

Transmission Input Shaft Sensing

Use Scenario: Detecting rotational position and speed of crankshaft in gasoline/diesel ICEs 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 for combustion cycle synchronization.

Use Value: High-temperature stability and differential output ensure reliable signal integrity despite engine bay EMI and thermal cycling.

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

IC Role / Device Role / Timing Role: Speed feedback element enabling closed-loop hydraulic pressure control and shift timing accuracy.

Use Value: Programmable hysteresis allows consistent triggering across worn gear teeth and variable air gaps encountered in high-mileage units.

Camshaft Position Detection

Hybrid Powertrain Motor Rotor Position

Use Scenario: Identifying cylinder-specific valve timing events in variable valve timing (VVT) systems.

IC Role / Device Role / Timing Role: Phase-reference sensor providing absolute cam position relative to crankshaft for intake/exhaust valve actuation sequencing.

Use Value: Built-in EEPROM calibration maintains phase accuracy after repeated thermal stress cycles, reducing drift-induced misfires.

Use Scenario: Sensing rotor position in 48 V mild-hybrid starter-generator assemblies for field-oriented control.

IC Role / Device Role / Timing Role: Low-latency speed and direction feedback source used by inverter gate driver logic for precise torque vectoring.

Use Value: ≤3 µs response time enables accurate commutation at motor speeds exceeding 15,000 RPM under transient load.

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 die, but in 3-pin TO-92 package without thermal pad; lower thermal dissipation capability.	Suitable for lower-power or cooler ambient locations (e.g., transmission case exterior vs. engine block).	Select when board space permits TO-92 mounting and peak junction temperature remains below 135 °C.
MLX90363KGO-ABA-000-RE	Triaxis® Hall IC with SPI interface and 360° angle measurement; no differential output or gear tooth counting logic.	Used for absolute angular position in EPS or throttle bodies - not drop-in for crank/cam speed sensing.	Choose only if system requires programmable angle reporting and can replace differential comparator logic with MCU-based decoding.

Compared with TLE4983CXTMA1, the TLE4983CHTNE6747HAMA1 offers superior thermal management for under-hood placement; versus MLX90363, it provides deterministic zero-latency edge detection essential for real-time ICE timing control, without requiring host processor intervention.

FAQ

What is the maximum air gap supported by TLE4983CHTNE6747HAMA1 for a standard 60-tooth steel gear?

At 24 V supply and 25 °C ambient, the device reliably detects gear teeth up to 2.5 mm air gap using a standard 60-tooth ferrous gear with 2 mm module. Performance degrades above this gap due to reduced magnetic flux density at the Hall plate, confirmed by Infineon's application note AN2605.

Does TLE4983CHTNE6747HAMA1 require an external pull-up resistor for differential output operation?

Yes - the OUT pin is open-drain and requires an external pull-up resistor (typically 4.7 kΩ) to V_BB for single-ended use; for differential mode, both OUT and OUTB must be pulled up with matched resistors to maintain common-mode rejection and noise immunity.

Can TLE4983CHTNE6747HAMA1 operate with a 3.3 V microcontroller I/O interface?

No - the device does not support 3.3 V logic-level interfacing. Its output is referenced to V_BB (4.5–24 V), and the open-drain structure requires pull-up to the same supply rail; level-shifting circuitry is mandatory for connection to 3.3 V MCUs.

Is the EEPROM in TLE4983CHTNE6747HAMA1 user-programmable during system integration?

No - the EEPROM is factory-programmed during final test and contains calibrated magnetic offset and sensitivity data. It is read-only during normal operation and cannot be rewritten in-field or via standard communication interfaces.
