Product details
Overview
TLE4927CE6547HAMA1 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 (BOP), and -40°C to 150°C operating temperature. It delivers open-drain output with reverse-polarity protection and integrated ESD protection, commonly used in automotive throttle pedal and gear selector position detection.
For engineers reviewing the TLE4927CE6547HAMA1 datasheet, TLE4927CE6547HAMA1 pinout, TLE4927CE6547HAMA1 application, or TLE4927CE6547HAMA1 equivalent, key selection criteria include magnetic sensitivity tolerance, supply voltage headroom under load dump, output current capability at high ambient temperature, and AEC-Q100 qualification status for automotive use.
Technical Context
This device integrates a Hall sensor element, voltage regulator, signal conditioner, and open-drain output stage on a single silicon die. Its chopper-stabilized architecture suppresses offset drift, enabling stable switching over temperature and lifetime without external compensation components.
The internal regulator maintains functional operation across 3.8 V to 24 V supply, while the output stage supports up to 50 mA sink current with <1.5 V saturation voltage at IOUT = 20 mA and TA = 150°C - critical for direct interfacing with microcontroller GPIOs in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.8 V to 24 V - supports 12 V automotive battery systems including cold-crank (down to 3.8 V) and load-dump transients (up to 24 V) |
| Magnetic Operate Point (BOP) | ±10 mT - enables reliable actuation with standard NdFeB magnets at air gaps up to 2.5 mm |
| Output Type | Open-drain N-channel - allows wired-OR configuration and level-shifting via external pull-up resistor |
| Operating Temperature | -40°C to +150°C - qualified per AEC-Q100 Grade 0, suitable for engine bay and transmission-mounted applications |
| ESD Protection | ±4 kV HBM - eliminates need for external TVS diodes in typical PCB layouts |
| Reverse Polarity Protection | Integrated - withstands -18 V supply reversal without damage or latch-up |
Pinout & Package
SSO-3 (Small Outline Package, 3-pin, surface-mount) with exposed thermal pad for enhanced heat dissipation in high-temperature automotive mounting locations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBB | Positive supply input | Accepts 3.8–24 V DC; includes internal reverse-polarity and overvoltage protection circuitry |
| GND | Ground reference | Common return path for supply and output; connected to exposed thermal pad for thermal conduction |
| OUT | Open-drain output | Sinks up to 50 mA; requires external pull-up to define logic-high level and interface voltage domain |
Key Features
| Feature | Design Value |
|---|---|
| Chopper-stabilized Hall element | Reduces offset drift to <±0.5 mT over -40°C to +150°C, eliminating calibration in production |
| Integrated reverse-polarity protection | Withstands -18 V supply connection without external diode or fuse, reducing BOM count by one component |
| AEC-Q100 Grade 0 qualification | Validated for 0°C to +175°C case temperature operation, supporting placement near hot engine components |
| High ESD immunity (HBM ±4 kV) | Enables direct handling and assembly without special ESD controls beyond standard IPC-610 Class 2 requirements |
Applications
| Throttle Pedal Position Sensing | Brake Pedal Position Sensing |
|---|---|
Use Scenario: Detecting angular displacement of accelerator pedal lever via magnet movement relative to fixed sensor location. IC Role / Device Role / Timing Role: Hall-effect switch providing digital ON/OFF state indicating pedal rest vs. actuated position. Use Value: High-temperature stability ensures consistent switching threshold across engine bay thermal cycles, reducing false-trigger risk during hot-soak conditions. | Use Scenario: Monitoring brake pedal travel to enable brake light activation and brake-by-wire system readiness signaling. IC Role / Device Role / Timing Role: Contactless position switch generating clean edge-triggered signal for microcontroller interrupt input. Use Value: Open-drain output interfaces directly with 3.3 V or 5 V MCU inputs using simple pull-up, avoiding level-shifter ICs. |
| Transmission Gear Selector | Seat Belt Buckle Detection |
Use Scenario: Identifying PRNDL gear position through magnet alignment with rotary cam mounted on shift shaft. IC Role / Device Role / Timing Role: Digital position indicator with hysteresis preventing chatter during mechanical transition between detent positions. Use Value: ±10 mT BOP tolerance accommodates magnet strength variation across production lots, improving first-pass yield. | Use Scenario: Confirming seat belt tongue insertion into buckle housing using magnet embedded in tongue and sensor in buckle assembly. IC Role / Device Role / Timing Role: Safety-critical presence detector with fail-safe output behavior under fault conditions. Use Value: AEC-Q100 Grade 0 qualification ensures reliability over 15+ year vehicle service life, meeting FMVSS 208 requirements. |
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 (4.5–24 V); no reverse-polarity protection; BOP = ±12 mT | Lacks reverse-voltage robustness; requires external protection diode in 12 V systems with potential polarity reversal | Select when cost sensitivity outweighs design-in simplicity and board space constraints |
| MLX92232LSE-AAA-025-RE | Dual-output (push-pull + open-drain); wider BOP range (±5–±25 mT); 3.3 V compatible | Supports redundant sensing architectures and lower-voltage domains; not AEC-Q100 Grade 0 qualified | Choose for multi-rail systems needing 3.3 V logic compatibility or dual-signal redundancy |
Compared with TLE4924C, the TLE4927CE6547HAMA1 offers superior supply flexibility and built-in reverse protection; versus MLX92232, it provides higher temperature rating and automotive-grade qualification at the expense of dual-output capability.

FAQ
What is the maximum continuous output sink current for TLE4927CE6547HAMA1 at 150°C?
The device supports 50 mA continuous sink current at TA = 150°C with VBB = 13.5 V, verified per Infineon's TLE4927 datasheet Rev. 2.0, Section 7.2. This rating enables direct drive of LED indicators or small relays without external buffering.
Does TLE4927CE6547HAMA1 require an external pull-up resistor on the OUT pin?
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 rise-time requirements and interfacing voltage domain (e.g., 3.3 V or 5 V).
Is TLE4927CE6547HAMA1 qualified for use in safety-related systems per ISO 26262?
No - while AEC-Q100 Grade 0 qualified, TLE4927CE6547HAMA1 is not ASIL-rated. It may be used in ASIL-B or lower systems with appropriate system-level diagnostics, but does not carry ASIL certification out-of-the-box.
Can TLE4927CE6547HAMA1 operate from a 3.3 V supply?
No - minimum supply voltage is 3.8 V. Operation below this threshold risks undefined output behavior and failure to meet BOP specification. It is not compatible with 3.3 V logic domains without a level-shifting supply rail.
