Product details
Overview
APS11760LLHALT-0SL from Allegro MicroSystems is a micropower vertical Hall-effect switch IC designed for automotive position sensing in harsh environments. It features unipolar south-sensing (BOP = ±40 G typ.), 6 µA average supply current at 12 V, open-drain output, and operates from –40°C to 150°C ambient temperature. It is used in gear shift selectors (PRNDL), clutch/brake position detection, and end-of-travel sensing where ultra-low power and AEC-Q100 qualification are critical.
For engineers reviewing the APS11760LLHALT-0SL datasheet, APS11760LLHALT-0SL pinout, APS11760LLHALT-0SL application, or APS11760LLHALT-0SL equivalent, this page delivers verified technical context, exact magnetic thresholds, micropower timing parameters, package-specific thermal resistance, and ASIL A–capable safety integration guidance per ISO 26262.
Technical Context
The APS11760LLHALT-0SL implements a vertical Hall sensing element sensitive to magnetic flux parallel to the IC face (X-axis), enabling compact side-approach mounting. 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 at 12 V.
It integrates dynamic offset cancellation, low-pass filtering, and Schmitt-trigger output logic with on-chip overvoltage (40 V load dump), reverse-battery (–18 V), and short-circuit protection. The device enters undervoltage lockout below 2.25 V and resets after 100 µs POR delay.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| APS11700LLHALT-0SL | Planar (Z-axis) sensing instead of vertical (X-axis); identical electrical specs, package, and micropower timing. | Requires top-approach magnet placement; unsuitable for side-actuated levers or rods. | Select APS11700LLHALT-0SL only when magnet orientation is perpendicular to PCB surface. |
| TLE4913-2K | Higher 12 µA avg. ICC; no ASIL A SEooC documentation; 150°C max junction temp (vs. 165°C). | Lacks functional safety evidence package; not validated for ISO 26262 integration in safety-critical PRNDL systems. | Choose TLE4913-2K only for non-safety subsystems where cost is prioritized over ASIL compliance. |
Compared with APS11700LLHALT-0SL, the APS11760LLHALT-0SL enables side-approach sensing in tight spaces, while versus TLE4913-2K it delivers certified ASIL A capability, lower power, and higher temperature margin-critical for transmission and chassis control units.

FAQ
What is the magnetic sensing axis orientation of the APS11760LLHALT-0SL?
The APS11760LLHALT-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 actuation-ideal for gear levers, pedals, and linear actuators where magnets move laterally past the sensor body. Unlike the planar APS11700 series, it does not require top-down magnetic field alignment.
Does the APS11760LLHALT-0SL support functional safety requirements for ASIL-rated systems?
Yes, the APS11760LLHALT-0SL was developed in accordance with ISO 26262 as a hardware safety element out-of-context (SEooC) with ASIL A capability (pending final confirmation). It includes documented failure modes, diagnostic coverage metrics, and safety manual guidance for integration into higher-ASIL systems using external diagnostics or redundancy-making it suitable for PRNDL and brake position applications.
What is the typical micropower timing behavior of the APS11760LLHALT-0SL?
The APS11760LLHALT-0SL operates with a 160 ms total micropower period (typ.), consisting of a 50 µs active "awake" window for Hall sampling and stabilization, followed by a 159.95 ms "sleep" interval. Output state is latched on the falling edge of the timing pulse and held constant during sleep-enabling 6 µA average current draw at 12 V and supporting decade-long battery life in always-on sensing nodes.
Can the APS11760LLHALT-0SL be used directly on a 24 V automotive battery rail?
Yes, the APS11760LLHALT-0SL is rated for 40 V absolute maximum supply voltage and includes on-chip protection for 40 V load dump transients, –18 V reverse battery, and output short-circuit events. Its internal regulator and robust front-end allow direct connection to unregulated 12 V or 24 V battery rails without external protection components-reducing system cost and board space.
What package type and pin configuration does the APS11760LLHALT-0SL use?
The APS11760LLHALT-0SL uses the 3-pin SOT23W surface-mount package (suffix LH), with pin 1 = VCC, pin 2 = VOUT, and pin 3 = GND (viewed from branded face). It is lead-free with 100% matte tin plating and has a thermal resistance of 110°C/W on a 2-layer PCB-optimized for high-density automotive PCB layouts requiring minimal thermal derating.
