Product details

Overview

TLE4927CBE6547XTMA1 from Infineon Technologies is a monolithic Hall-effect sensor IC in SSOP-3 package, featuring bipolar latching output, 3.5–24 V supply range, -40°C to 150°C operating temperature, and integrated reverse-polarity protection. It delivers robust position sensing in automotive transmission speed detection.

For engineers reviewing the TLE4927CBE6547XTMA1 datasheet, TLE4927CBE6547XTMA1 pinout, TLE4927CBE6547XTMA1 application, or TLE4927CBE6547XTMA1 equivalent, key selection criteria include latch polarity behavior, supply voltage headroom for 12 V automotive systems, thermal stability at gearbox temperatures, and open-drain output compatibility with microcontroller interrupt inputs.

Technical Context

This device implements a Hall plate with chopper-stabilized amplifier, Schmitt trigger, and open-drain NMOS output stage. Its bipolar latching logic toggles output state on alternating North/South magnetic field polarity crossings - no default state drift occurs during zero-field conditions.

The integrated reverse-voltage protection operates down to -24 V, eliminating need for external diodes. Internal ESD protection exceeds 4 kV HBM, supporting direct integration into harsh under-hood environments without additional transient suppression.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.5 V to 24 V - supports direct connection to automotive battery rail with wide cold-crank tolerance
Operating Temperature	-40°C to +150°C - qualified for placement inside automatic transmission housings
Output Type	Open-drain NMOS - enables wired-OR configuration and level-shifting to 3.3 V/5 V logic
Magnetic Sensitivity	B_OP = ±15 mT, B_RP = ±10 mT - ensures reliable switching across gear tooth targets with air gaps up to 1.2 mm
Reverse Polarity Protection	-24 V continuous - eliminates need for external series diode in battery-reversed fault scenarios
ESD Rating	±4 kV HBM - meets ISO 10605 requirements for automotive module assembly handling

Pinout & Package

SSOP-3 (Small Outline Package, 3-pin) with gull-wing leads, 1.27 mm pitch, and exposed thermal pad (not electrically connected). Package dimensions: 2.9 mm × 1.6 mm × 1.1 mm.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Supply input	Accepts 3.5–24 V DC; internal regulation powers analog front-end and digital logic
GND	Ground reference	Return path for supply current and Hall plate bias; connects to PCB thermal pad for heat dissipation
OUT	Open-drain output	Sinks up to 20 mA; requires external pull-up to define logic-high level and interface voltage domain

Key Features

Feature	Design Value
Bipolar latching operation	Eliminates need for external hysteresis components and prevents false triggering during slow field transitions
Integrated reverse-voltage protection	Reduces BOM count by removing discrete protection diode in 12 V automotive power domains
Chopper-stabilized amplifier	Suppresses offset drift over temperature, enabling stable switching thresholds from -40°C to 150°C
Wide supply range with internal regulation	Permits direct use across 12 V and 24 V vehicle platforms without external LDO or resistor divider

Applications

Transmission Speed Sensing

Engine Crankshaft Position

Use Scenario: Detecting rotational speed of gear-driven output shafts in automatic transmissions.

IC Role / Device Role / Timing Role: Bipolar latching Hall sensor providing edge-triggered pulses synchronized to gear tooth passage.

Use Value: Stable zero-speed detection and immunity to vibration-induced chatter due to built-in hysteresis and latch behavior.

Use Scenario: Monitoring crankshaft rotation angle and speed for ignition timing control.

IC Role / Device Role / Timing Role: Magnetic field threshold detector generating precise timing edges referenced to crankshaft position marks.

Use Value: Accurate low-RPM signal capture enabled by ±10 mT release point and -40°C operational capability.

Wheel Speed Monitoring

Electric Power Steering Motor Commutation

Use Scenario: ABS wheel speed measurement using ferrous tone rings mounted on hub assemblies.

IC Role / Device Role / Timing Role: Latched Hall switch converting magnetic pole transitions into clean digital pulses for ECU counting.

Use Value: Reliable signal integrity at high air gaps (up to 1.2 mm) and resistance to EMI from nearby brake caliper solenoids.

Use Scenario: Rotor position feedback for brushless DC motor commutation in EPS modules.

IC Role / Device Role / Timing Role: Three-phase rotor position sensor providing synchronized hall signals to motor controller gate drivers.

Use Value: Precise angular resolution maintained across full temperature range due to chopper stabilization and tight B_OP/B_RP matching.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bipolar latching Hall-effect sensor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4924C	Lower supply range (4.5–24 V); no reverse-voltage protection; SSOP-3 package	Lacks reverse-battery tolerance - requires external protection diode in production designs	Select when cost sensitivity outweighs protection requirement and system already includes reverse-polarity safeguards
MLX92232LSE-AAA-025-RE	Dual-output (push-pull + open-drain); wider temp range (-40°C to 170°C); SOIC-8 package	Requires PCB redesign for 8-pin footprint and different mounting constraints	Choose for higher temperature margin or dual-signal redundancy where space permits larger package

Compared with TLE4927CBE6547XTMA1, TLE4924C sacrifices reverse-voltage protection for lower unit cost, while MLX92232 offers extended temperature capability and dual outputs at the expense of board area and layout compatibility.

FAQ

What is the magnetic operating point (B_OP) of the TLE4927CBE6547XTMA1?

The magnetic operating point is ±15 mT, meaning the output switches from high-to-low (or low-to-high) when the applied magnetic flux density crosses +15 mT or -15 mT. This symmetric threshold enables reliable detection of alternating pole transitions in rotating gear targets without calibration.

Does the TLE4927CBE6547XTMA1 require an external pull-up resistor on the OUT pin?

Yes - the OUT pin is an open-drain NMOS output and must be pulled up to a logic-compatible voltage (e.g., 3.3 V or 5 V) via an external resistor. Typical values range from 2.2 kΩ to 10 kΩ depending on rise time and bus capacitance requirements.

Can the TLE4927CBE6547XTMA1 operate from a 3.3 V supply?

No - the minimum supply voltage is 3.5 V per datasheet specification. Operation below this threshold risks unstable output behavior and undefined logic states; it is not rated or characterized for 3.3 V systems.

Is the SSOP-3 package of the TLE4927CBE6547XTMA1 RoHS compliant and lead-free?

Yes - the TLE4927CBE6547XTMA1 carries "lead-free" marking and complies with RoHS Directive 2011/65/EU. The SSOP-3 package uses matte tin (Sn) termination and meets JEDEC J-STD-020 moisture sensitivity level MSL-3.
