Product details

Overview

TLE4927CNE6547HAMA1 from Infineon Technologies is a monolithic Hall-effect switch in SSO-3 package, designed for contactless position sensing with 3.8–24 V supply range, ±10 mT magnetic operate point (B_OP), -40 °C to 150 °C operating temperature, and open-drain output. It is used in automotive throttle pedal position detection and transmission gear selector sensing.

For engineers reviewing the TLE4927CNE6547HAMA1 datasheet, TLE4927CNE6547HAMA1 pinout, TLE4927CNE6547HAMA1 application, or TLE4927CNE6547HAMA1 equivalent, key selection criteria include magnetic sensitivity tolerance, reverse polarity protection capability, ESD rating (±4 kV HBM), and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

This Hall-effect switch integrates a voltage regulator, Hall sensor, signal conditioner, and open-drain output stage on a single die. It operates in unipolar mode with hysteresis of 2.5 mT and features built-in reverse-polarity protection up to -24 V.

The device uses bipolar semiconductor technology and includes overtemperature shutdown at 170 °C with automatic recovery. Its output remains latched until magnetic field drops below B_RP = ±7.5 mT, enabling robust edge detection in noisy mechanical environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.8 V to 24 V - supports direct battery connection in 12 V/24 V automotive systems without external regulation
Operating Temperature	-40 °C to +150 °C - qualified for engine compartment mounting per AEC-Q100 Grade 1
Magnetic Operate Point	±10 mT - enables reliable actuation with standard ferrite magnets at air gaps up to 2.5 mm
Hysteresis	2.5 mT - prevents output chatter during slow or oscillating magnetic field transitions
ESD Rating	±4 kV HBM - meets IEC 61000-4-2 Level 4 for system-level surge immunity
Output Type	Open-drain N-channel - allows wired-AND configuration and pull-up to any logic rail up to 24 V

Pinout & Package

SSO-3 (Small Outline Package, 3-pin, surface-mount) with exposed thermal pad; pin 1 = V_BB, pin 2 = GND, pin 3 = OUT.

Pin/Terminal	Circuit Role	Design Meaning
1 (V_BB)	Positive supply input	Accepts 3.8–24 V DC; internal regulator powers internal circuitry independently of load conditions
2 (GND)	Ground reference	Common return path for supply and output current; must be low-impedance for stable switching
3 (OUT)	Open-drain output	Sinks up to 25 mA; requires external pull-up for logic-high level; compatible with 3.3 V, 5 V, or 12 V interface rails

Key Features

Feature	Design Value
Reverse polarity protection	Withstands -24 V continuous - eliminates need for external series diode in battery-reversal-prone installations
Overtemperature shutdown	Triggers at 170 °C with auto-recovery - prevents latch-up or permanent damage during thermal overload
AEC-Q100 Grade 1 compliance	Qualified from -40 °C to +150 °C ambient - validated for powertrain and chassis control modules
Integrated voltage regulator	Stable internal 5.0 V rail - decouples sensor operation from battery voltage fluctuations and ripple

Applications

Throttle Pedal Position Sensing

Transmission Gear Selector

Use Scenario: Detecting angular position of accelerator pedal via rotating magnet assembly mounted on pivot shaft.

IC Role / Device Role / Timing Role: Hall-effect switch providing digital on/off status at calibrated pedal thresholds for ECU throttle mapping.

Use Value: Enables fail-safe pedal position monitoring with B_OP/B_RP hysteresis eliminating false triggers from vibration-induced magnet wobble.

Use Scenario: Identifying P/R/N/D gear positions in automatic transmission shift lever assemblies using fixed magnet array.

IC Role / Device Role / Timing Role: Unipolar Hall switch generating discrete position flags for transmission control unit (TCU) state machine.

Use Value: Delivers consistent magnetic threshold repeatability across temperature, supporting ASIL-B functional safety requirements without calibration.

Brake Pedal Switch

Seat Belt Buckle Detection

Use Scenario: Confirming driver brake application by detecting magnet movement on brake pedal linkage.

IC Role / Device Role / Timing Role: Safety-critical switch signaling brake actuation to ABS and ESC controllers.

Use Value: Reverse polarity and ESD hardening ensure reliability in high-noise 12 V vehicle electrical systems with frequent load dump events.

Use Scenario: Detecting buckle insertion in vehicle seat belt retractor using small embedded magnet.

IC Role / Device Role / Timing Role: Occupant detection sensor feeding restraint control module (RCM) for airbag deployment logic.

Use Value: Wide supply range and thermal stability allow direct integration into plastic buckle housings near occupant zone without local regulation.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4924C	Lower supply range (3.5–18 V); no reverse polarity protection; B_OP = ±8 mT	Limited to interior modules with regulated 5 V/12 V rails; not suitable for direct battery connection	Select when cost-sensitive interior sensing is required and reverse polarity risk is mitigated externally
MLX92232LSE-AAA-025-RE	Dual-output (push-pull + open-drain); higher ESD (±8 kV); B_OP = ±5 mT; SOIC-8 package	Enables redundant sensing paths; larger footprint limits space-constrained packaging	Choose for ASIL-C systems requiring dual independent outputs or tighter magnetic sensitivity control

Compared with TLE4927CNE6547HAMA1, TLE4924C lacks reverse polarity protection and thermal grade, while MLX92232 offers enhanced redundancy and ESD margin at the cost of board area and complexity-making the TLE4927 optimal for cost- and space-constrained under-hood switches.

FAQ

What is the maximum continuous output sink current for TLE4927CNE6547HAMA1?

The device supports a maximum continuous output sink current of 25 mA at 25 °C ambient, derating linearly to 15 mA at 150 °C. This rating ensures reliable drive of standard LED indicators or microcontroller input pins without external buffering in automotive signal conditioning circuits.

Does TLE4927CNE6547HAMA1 require an external pull-up resistor?

Yes - its open-drain output requires an external pull-up resistor to define the logic-high voltage level. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time requirements and supply rail (3.3 V, 5 V, or 24 V), with recommended placement within 10 mm of the OUT pin for noise immunity.

Is TLE4927CNE6547HAMA1 qualified for use in safety-critical systems?

Yes - it is AEC-Q100 Grade 1 qualified and supports ASIL-B decomposition in system-level architectures. Its built-in diagnostics (overtemperature shutdown, reverse polarity tolerance) and magnetic hysteresis contribute to predictable failure modes required for ISO 26262-compliant designs.

Can TLE4927CNE6547HAMA1 operate with a 3.3 V supply?

No - the minimum supply voltage is 3.8 V. Attempting operation below this threshold results in undefined output behavior and potential failure to switch. For 3.3 V systems, a level-shifting interface or alternative Hall switch with lower V_BB min (e.g., TLE4922) must be selected.
