Product details

Overview

TLE4924C1NE6547HAMA1 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-used in automotive throttle pedal and gear selector position detection.

For engineers reviewing the TLE4924C1NE6547HAMA1 datasheet, TLE4924C1NE6547HAMA1 pinout, TLE4924C1NE6547HAMA1 application, or TLE4924C1NE6547HAMA1 equivalent, key selection factors include magnetic sensitivity tolerance, reverse polarity protection, integrated output clamp diode, and AEC-Q100 Grade 1 qualification for under-hood deployment.

Technical Context

This device integrates a Hall sensor, voltage regulator, signal conditioner, and open-drain N-channel output stage on a single silicon die. It operates in unipolar switching mode with programmable hysteresis (typically 2.5 mT) and features built-in ESD protection (>2 kV HBM) and overvoltage clamp at 40 V.

The internal regulator enables stable operation across wide input voltage swings, while the output stage supports sink currents up to 50 mA and interfaces directly with 3.3 V or 5 V microcontrollers without external pull-up resistors.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	3.8 V to 24 V - supports direct battery connection in 12 V automotive systems with transient tolerance
Operating Temperature	-40°C to +150°C - qualified for engine compartment mounting per AEC-Q100 Grade 1
Magnetic B_OP	±10 mT typ. - enables reliable actuation with standard NdFeB magnets at air gaps ≤2 mm
Output Type	Open-drain N-channel - allows wired-OR configuration and direct interface to MCU GPIO
Reverse Polarity Protection	Integrated - eliminates need for external series diode in battery-reversed fault conditions
ESD Rating	±2 kV HBM - meets automotive system-level ESD immunity requirements without additional protection circuitry

Pinout & Package

SSO-3-92 is a 3-pin, surface-mount, leadless package with exposed thermal pad; dimensions 2.9 mm × 2.5 mm × 0.9 mm (L × W × H), pitch 1.27 mm.

Pin/Terminal	Circuit Role	Design Meaning
V_BB	Supply Input	Connects to battery rail; includes internal reverse-polarity and overvoltage protection
GND	Ground Reference	Low-impedance return path for sensor core and output stage; tied to thermal pad
OUT	Open-Drain Output	Sinks current when magnetic field exceeds B_OP; requires external pull-up for logic-high state

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4924C2NE6547HAMA1	B_OP = ±15 mT (higher sensitivity threshold); same package and pinout	Better suited for larger air gaps or weaker magnets; less immune to stray field interference	Select when magnet strength varies significantly or mechanical tolerances exceed ±0.3 mm
TLV4924C1HALA1	SSO-3-92 package, but rated only to 125°C ambient and not AEC-Q100 qualified	Limited to cabin or non-powertrain locations; unsuitable for under-hood use	Choose only for cost-sensitive consumer or industrial applications outside automotive qualification scope

Compared with TLE4924C2NE6547HAMA1, the original offers tighter magnetic threshold control for precision pedal sensing; versus TLV4924C1HALA1, it delivers full automotive reliability with extended temperature capability and qualification traceability.

FAQ

What is the maximum continuous output sink current for TLE4924C1NE6547HAMA1?

The device supports a continuous output sink current of 50 mA at T_A = 25°C, derating linearly to 25 mA at 150°C. This rating assumes proper PCB copper area for thermal dissipation and accounts for internal power dissipation limits of the integrated N-channel MOSFET output stage.

Does TLE4924C1NE6547HAMA1 require an external pull-up resistor on the OUT pin?

Yes-an external pull-up resistor is mandatory on the OUT pin to define the logic-high voltage level. Typical values range from 2.2 kΩ to 10 kΩ, selected based on rise time requirements and MCU input leakage; the internal output stage is open-drain only and cannot drive high.

Can TLE4924C1NE6547HAMA1 operate from a 5 V supply?

No-it is not specified for 5 V operation. The minimum supply voltage is 3.8 V, but its internal regulator and protection circuitry are optimized for 12 V automotive battery systems; operation below 6 V may result in undefined switching behavior or failure to meet AEC-Q100 parametric limits.

Is there a recommended PCB layout guideline for thermal performance?

Yes-Infineon recommends connecting the exposed thermal pad to a minimum 100 mm² copper pour on the top layer, thermally vias (≥4×0.3 mm) to inner ground planes, and avoiding solder mask over the pad. This achieves ≤45°C/W junction-to-ambient thermal resistance in standard 2-layer boards.
