Product details
Overview
APS11760LLHALX-0SL from Allegro MicroSystems is a micropower vertical Hall-effect switch IC designed for automotive position sensing in harsh environments. It features unipolar south polarity, 6 µA average supply current at 12 V/25°C, ±40 G operate point, and operates from –40°C to 150°C ambient temperature. It serves as a solid-state replacement for reed switches in gear selectors and door/lid open-close detection.
For engineers reviewing the APS11760LLHALX-0SL datasheet, APS11760LLHALX-0SL pinout, APS11760LLHALX-0SL application, or APS11760LLHALX-0SL equivalent, key selection criteria include its X-axis (parallel-to-package-face) magnetic sensitivity, AEC-Q100 qualification, ASIL A SEooC safety capability, open-drain output with 25 mA short-circuit current limit, and 3-pin SOT23W surface-mount package compatibility.
Technical Context
The APS11760LLHALX-0SL implements a chopper-stabilized vertical Hall sensor with dynamic offset cancellation and a low-pass filter to reject EMI. Its micropower architecture cycles between 50 µs awake time and 160 ms sleep period (typ.), achieving 0.03% duty cycle and 6 µA average ICC.
It integrates on-chip protection including 40 V load dump tolerance, reverse-battery clamping at –18 V, output short-circuit current limiting (25 mA typ.), and ±11 kV HBM ESD immunity. The device uses an internal undervoltage lockout (UVLO) with 2.25 V enable and 2.5 V release thresholds, active only during awake periods.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| APS11760LLHALT-0SL | Same electrical specs but supplied in 7-in. reel (3,000 pcs); identical SOT23W package and X-axis sensing | No functional difference; differs only in packaging format (reel size) | Select when smaller reels align with SMT line feed requirements or lower initial inventory commitment is needed. |
| TLE4913-2K | Infineon bipolar Hall switch with 3.0–24 V range, 3.5 mA ICC, and –40°C to 150°C rating; no micropower mode | Lacks 6 µA sleep current and ASIL A SEooC documentation; suited for non-safety-critical, higher-power subsystems | Choose where continuous sensing is required and power budget permits >3 mA average draw. |
Compared with APS11760LLHALX-0SL, APS11760LLHALT-0SL offers identical performance in a different reel format, while TLE4913-2K provides comparable ruggedness but lacks micropower operation and functional safety evidence-making it suitable only for non-ASIL applications where constant monitoring is mandatory.

FAQ
What is the magnetic sensing orientation of the APS11760LLHALX-0SL?
The APS11760LLHALX-0SL features a vertical Hall-effect sensing element sensitive to magnetic flux parallel to the face of the IC package (X-axis). This enables side-approach magnet mounting, unlike planar (Z-axis) devices such as the APS11700 series. The sensing direction is confirmed in the functional block diagram and selection guide, where APS11760 denotes X-axis orientation.
Does the APS11760LLHALX-0SL support unipolar or omnipolar magnetic field detection?
The APS11760LLHALX-0SL is configured for unipolar south (S) detection, indicated by the "SL" in its part number suffix. It activates when a south-polarity magnetic field exceeds +40 G (typ.) and releases below +22.5 G (typ.). It does not respond to north-polarity fields, distinguishing it from omnipolar variants like APS11760LLHALX-0PL.
What protection features are integrated into the APS11760LLHALX-0SL?
The APS11760LLHALX-0SL integrates reverse-battery protection (–18 V clamp), 40 V load dump tolerance, output short-circuit current limiting (25 mA typ.), and ±11 kV HBM ESD immunity. These protections eliminate the need for external TVS diodes, reverse-polarity MOSFETs, or current-limiting resistors in typical automotive deployments.
Is the APS11760LLHALX-0SL qualified for automotive safety applications?
Yes-the APS11760LLHALX-0SL is developed as a hardware safety element out-of-context (SEooC) with ASIL A capability per ISO 26262 (pending final confirmation), and is AEC-Q100 qualified for Grade 0 (–40°C to +150°C). Safety integration requires adherence to the manufacturer's safety manual and datasheet guidelines.
What is the typical supply current and micropower period of the APS11760LLHALX-0SL?
The APS11760LLHALX-0SL draws 6 µA average supply current at 12 V/25°C with a typical micropower period of 160 ms, comprising a 50 µs awake window for sampling and a 159.95 ms sleep interval. This yields a 0.03% duty cycle, enabling multi-year operation in energy-constrained battery-powered systems.
