Product details

Overview

TLE4924C2NE6547HAMA1 from Infineon Technologies is a monolithic Hall-effect switch in SSO-3-92 package, designed for contactless position sensing with 3.8–24 V supply range, ±10 mT magnetic operate point (B_OP), and -40°C to 150°C operating temperature. It delivers open-drain output with reverse polarity protection and is used in automotive throttle pedal position detection.

For engineers reviewing the TLE4924C2NE6547HAMA1 datasheet, TLE4924C2NE6547HAMA1 pinout, TLE4924C2NE6547HAMA1 application, or TLE4924C2NE6547HAMA1 equivalent, key selection criteria include magnetic sensitivity tolerance, supply voltage headroom at cold cranking, output current capability under load, and AEC-Q100 qualification status for automotive use.

Technical Context

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

The device uses chopper-stabilized architecture to suppress offset drift and enable stable switching over temperature and supply variations. Its output remains latched until magnetic field drops below release threshold (B_RP = ±7.5 mT), supporting robust edge detection in noisy mechanical environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.8 V to 24 V - supports full automotive battery range including cold-crank dips and load-dump transients
Operating Temperature	-40°C to +150°C - qualified for engine compartment and transmission-mounted applications
Magnetic Operate Point	±10 mT - enables reliable actuation with standard ferrite magnets at air gaps up to 2.5 mm
Output Type	Open-drain N-channel - allows wired-OR configuration and direct interface to 3.3 V/5 V microcontrollers
Hysteresis	±2.5 mT - prevents chatter during slow or oscillating magnetic field transitions
AEC-Q100 Grade	Grade 0 - certified for safety-critical powertrain and chassis systems

Pinout & Package

SSO-3-92 is a 3-pin, surface-mount, leadless package with exposed thermal pad, optimized for high-temperature automotive PCB mounting and automated optical inspection.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4924C2E6547HAMA1	Same die, different tape-and-reel marking; identical electrical specs and qualification	No functional difference; used interchangeably in production	Select when sourcing from alternate reel lot codes or legacy inventory
TLV4924C2NE6547HAMA1	Same functionality but with extended -40°C to +170°C temp range and higher ESD rating (±6 kV HBM)	Required for under-hood applications exceeding 150°C ambient (e.g., turbocharger proximity)	Choose for next-gen thermal-critical designs where Grade 0 +170°C operation is mandated

Compared with TLE4924C2NE6547HAMA1, the TLV4924C2NE6547HAMA1 extends thermal capability for extreme under-hood placement, while the TLE4924C2E6547HAMA1 offers identical performance in standard automotive zones-both retain pinout, footprint, and diagnostic behavior.

FAQ

What is the maximum output sink current for TLE4924C2NE6547HAMA1?

The device supports a continuous output sink current of 25 mA at 25°C ambient, derating linearly to 15 mA at 150°C junction temperature. This enables direct driving of LED indicators or interfacing with standard microcontroller inputs without external buffering, provided the external pull-up resistor limits total current within spec.

Does TLE4924C2NE6547HAMA1 require an external pull-up resistor?

Yes - the 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 bus capacitance and rise-time requirements. No internal pull-up is integrated; omission results in undefined output state during high-impedance phase.

Is TLE4924C2NE6547HAMA1 qualified for ASIL-B systems?

While not ASIL-B certified as a standalone component, its AEC-Q100 Grade 0 qualification, built-in hysteresis, and chopper stabilization support integration into ASIL-B architectures when combined with system-level diagnostics per ISO 26262. Functional safety validation must be performed at the ECU level.

Can TLE4924C2NE6547HAMA1 operate with a 3.3 V supply?

No - the minimum supply voltage is 3.8 V. Operation below this threshold risks incomplete internal regulation, unstable switching thresholds, and potential non-compliance with B_OP/B_RP specifications. For 3.3 V systems, consider Infineon's TLV4913 series or externally regulated 5 V rail feeding this device.
