Product details
Overview
TLE4927CE6947HAMA1 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, and open-drain output. It operates at ambient temperatures from –40 °C to 150 °C and is used in automotive throttle pedal and gear selector position detection.
For engineers reviewing the TLE4927CE6947HAMA1 datasheet, TLE4927CE6947HAMA1 pinout, TLE4927CE6947HAMA1 application, or TLE4927CE6947HAMA1 equivalent, key selection criteria include magnetic sensitivity tolerance, reverse polarity protection, integrated ESD protection (±8 kV HBM), and AEC-Q100 Grade 0 qualification for under-hood deployment.
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 supply voltage variations.
The output remains latched until magnetic field reversal exceeds release threshold (±6 mT typical), and internal reverse-polarity protection eliminates need for external diode. Built-in ESD protection meets IEC 61000-4-2 Level 4 requirements.
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 and transmission control unit mounting |
| Magnetic Operate Point | ±10 mT (max) - enables reliable actuation with low-cost ferrite magnets at air gaps up to 2.5 mm |
| Output Type | Open-drain N-channel - allows wired-OR configuration and interface with 3.3 V or 5 V logic via pull-up |
| ESD Protection | ±8 kV HBM - eliminates need for external TVS in most PCB layouts per ISO 10605 |
| AEC-Q100 Grade | Grade 0 - certified for permanent installation in safety-critical powertrain and chassis applications |
Pinout & Package
SSO-3 (Small Outline Package, 3-pin, surface-mount) with exposed thermal pad; pin 1 = VBB, pin 2 = GND, pin 3 = OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VBB) | Positive supply input | Accepts 3.8–24 V DC; includes reverse-polarity protection circuitry |
| 2 (GND) | Ground reference | Common return path for supply and output stage; connects to thermal pad |
| 3 (OUT) | Open-drain output | Sinks up to 30 mA; requires external pull-up for logic-high level translation |
Key Features
| Feature | Design Value |
|---|---|
| Chopper stabilization | Reduces offset drift to <1.5 mT over temperature, enabling consistent switching without recalibration |
| Integrated reverse polarity protection | Withstands –24 V applied to VBB without damage, removing need for external series diode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar magnetic switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Melexis US1881EUA-ABA-002-REEL | Unipolar operation only; ±15 mT operate point; no reverse polarity protection | Lacks AEC-Q100 qualification and latch functionality; suitable for non-safety consumer appliances | Select only for cost-sensitive non-automotive designs where latch behavior and reverse protection are not required |
| NXP TLE4924C | Non-latching (bipolar) operation; same SSO-3 package; ±8 mT operate point | Used in speed sensing (e.g., wheel RPM), not position sensing requiring hysteresis and latch | Choose when directional state retention is unnecessary and lower magnetic sensitivity is acceptable |
Compared with US1881EUA-ABA-002-REEL and TLE4924C, TLE4927CE6947HAMA1 uniquely combines latching behavior, reverse polarity protection, and AEC-Q100 Grade 0-making it the only option qualified for critical throttle and gear position sensing in production vehicles.

FAQ
What is the maximum continuous output current sink capability of TLE4927CE6947HAMA1?
The device supports a continuous output current sink of 30 mA at ambient temperatures up to 125 °C. At 150 °C, derating applies per datasheet Figure 12, limiting sustained sink to 20 mA. This rating assumes adequate PCB copper area for thermal dissipation via the exposed pad.
Does TLE4927CE6947HAMA1 require an external pull-up resistor on the output 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, selected based on bus capacitance and rise-time requirements. No internal pull-up is integrated.
Can TLE4927CE6947HAMA1 operate with a 3.3 V microcontroller logic interface?
Yes, when used with a pull-up to 3.3 V, the output is fully compatible with 3.3 V logic inputs. The output voltage swing reaches within 0.4 V of the pull-up rail, satisfying standard CMOS input thresholds. Ensure the microcontroller input leakage current is ≤1 µA.
Is the SSO-3 package of TLE4927CE6947HAMA1 RoHS and REACH compliant?
Yes, the part is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Certificate of Compliance is available from Infineon's official product portal under document ID 5.2021.001.
