Product details
Overview
TLE4983CHTE6547HAMA1 from Infineon Technologies is a monolithic Hall-effect speed and direction sensor in 3-pin SSO package, featuring differential output, programmable hysteresis (±0.5 mT typical), and operation up to 160 kHz at air gap ≤1.5 mm. It delivers robust rotational sensing for automotive crankshaft and camshaft position detection under harsh ECU environments.
For engineers reviewing the TLE4983CHTE6547HAMA1 datasheet, TLE4983CHTE6547HAMA1 pinout, TLE4983CHTE6547HAMA1 application, or TLE4983CHTE6547HAMA1 equivalent, key selection criteria include magnetic sensitivity tolerance, output phase accuracy over temperature (−40°C to 150°C), supply voltage range (4.5–24 V), and AEC-Q100 Grade 0 qualification status.
Technical Context
The TLE4983CHTE6547HAMA1 integrates a Hall plate, chopper-stabilized amplifier, Schmitt trigger, and open-drain output driver in a single die. Its differential architecture rejects common-mode magnetic interference and enables precise edge detection on rotating ferrous targets.
Programmable hysteresis and adaptive offset compensation ensure stable switching across mechanical tolerances and temperature drift. The device supports both static and dynamic magnetic field evaluation via its dual-output configuration (OUTP/OUTN), enabling direction discrimination without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 24 V - supports direct battery connection with reverse-polarity and load-dump protection |
| Operating Temperature | −40°C to +150°C - qualified for under-hood engine control module placement |
| Output Type | Differential open-drain (OUTP/OUTN) - enables noise-immune signal transmission over PCB traces ≥10 cm |
| Switching Frequency | Up to 160 kHz - sufficient for 8-cylinder engines at 12,000 RPM crankshaft speed |
| Magnetic Hysteresis | Programmable ±0.5 mT (typ.) - reduces chatter during low-speed or misaligned target conditions |
| AEC-Q100 Grade | Grade 0 - validated for permanent installation in safety-critical powertrain systems |
Pinout & Package
Package: 3-pin SSO (Small Outline Sensor), surface-mount, thermally enhanced leadframe, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Positive supply input | Accepts 4.5–24 V DC; internal clamp diode protects against transients up to ±40 V |
| GND | Reference ground | Low-impedance return path; shares thermal pad for junction-to-board heat dissipation |
| OUTP / OUTN | Differential output pair | Complementary open-drain outputs; require external pull-up to VDD for logic-level compatibility |
Key Features
| Feature | Design Value |
|---|---|
| Differential Hall sensing | Rejects uniform magnetic interference >90% - critical for engine bay EMI resilience |
| Chopper stabilization | Reduces offset drift to <±0.2 mT over full temperature range - ensures consistent air-gap margin |
| Programmable hysteresis | Configurable via external resistor - allows tuning for gear tooth geometry and vibration profile |
| Integrated ESD protection | HBM ±8 kV on all pins - eliminates need for external TVS in most engine harness layouts |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic speed and direction sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4983CJME6547HAMA1 | Same die, different package: 3-pin SIP instead of SSO; no thermal pad; lower power dissipation capability | Suitable for less thermally demanding locations (e.g., gearbox housing vs. cylinder head) | Select when board space permits larger footprint and thermal design does not require SSO's enhanced conduction path |
| TLV4983CQME6547HAMA1 | Same functional block, but QFN-8 package with exposed thermal pad and separate GND/VDD pins for improved EMC performance | Preferred for new designs requiring higher immunity in 48 V mild-hybrid ECUs | Choose when layout allows QFN routing and system-level EMC testing shows marginal margin with SSO variant |
Compared with TLE4983CJME6547HAMA1 and TLV4983CQME6547HAMA1, the TLE4983CHTE6547HAMA1 offers optimal thermal resistance (RthJA = 120 K/W) and minimal PCB footprint for high-density engine control modules where airflow is restricted.

FAQ
What is the maximum air gap supported by TLE4983CHTE6547HAMA1?
The TLE4983CHTE6547HAMA1 supports up to 1.5 mm air gap with standard ferrous target (e.g., 42CrMo4 steel gear) at 24 V supply and 25°C ambient. Performance degrades linearly beyond this point; at 2.0 mm, minimum detectable frequency drops to ~80 kHz due to reduced flux density at the Hall plate.
Does TLE4983CHTE6547HAMA1 require an external pull-up resistor?
Yes - both OUTP and OUTN are open-drain outputs and require external pull-up resistors to VDD. Typical value is 4.7 kΩ; values between 2.2 kΩ and 10 kΩ maintain rise time <100 ns while limiting current draw to <5 mA per output at 24 V.
Can TLE4983CHTE6547HAMA1 operate with 3.3 V logic interface?
No - the device requires minimum 4.5 V supply and has no 3.3 V-compatible I/O. Its outputs swing rail-to-rail with VDD; interfacing with 3.3 V microcontrollers requires level-shifting circuitry or a compatible differential receiver (e.g., MAX3095) powered from VDD.
Is TLE4983CHTE6547HAMA1 qualified for ISO 26262 ASIL-B compliance?
The TLE4983CHTE6547HAMA1 itself is not ASIL-B certified as a standalone component, but it is AEC-Q100 Grade 0 qualified and widely deployed in ASIL-B subsystems (e.g., engine control) when integrated with fault-tolerant MCU supervision, redundancy checks, and diagnostic software per ISO 26262 Part 5.
