Product details
Overview
APS11700LLHALT-0PL from Allegro MicroSystems is an AEC-Q100 qualified, ASIL A-capable micropower Hall-effect switch with omnipolar magnetic sensing (±40 G operate/release), 6 µA average supply current at 12 V, open-drain output, and Z-axis (perpendicular) sensitivity-designed for automotive gear position detection, door/lid open-close sensing, and clutch/brake position monitoring in harsh environments up to 165°C junction temperature.
For engineers reviewing the APS11700LLHALT-0PL datasheet, APS11700LLHALT-0PL pinout, APS11700LLHALT-0PL application, or APS11700LLHALT-0PL equivalent, key selection criteria include its omnipolar switching behavior, 3.3–24 V operation, 6 µA micropower sleep mode, SOT23W package compatibility, and integrated protection against load dump (40 V), reverse battery (−18 V), and output short-circuit.
Technical Context
The APS11700LLHALT-0PL implements a chopper-stabilized Hall sensor with dynamic offset cancellation and low-pass filtering to ensure stable switching across −40°C to +150°C ambient. Its micropower architecture cycles between 50 µs awake time and 160 ms sleep period, enabling ultra-low ICC(AVG) = 6 µA while maintaining robust magnetic response.
It features an open-drain NMOS output with VOUT(SAT) ≤ 500 mV at 5 mA, IOUTOFF ≤ 0.1 µA at 12 V, and built-in undervoltage lockout (VCC(UV)EN = 2.25 V, VCC(UV)DIS = 2.5 V) active only during awake intervals-ensuring reliable power-on behavior and fault resilience in unregulated automotive battery systems.
Key Specifications

Applications
| PRNDL Gear Selector | Trunk/Lid Open-Close Sensor |
|---|---|
Use Scenario: Detects rotational position of automatic transmission shift lever using embedded magnet and fixed sensor mounting. IC Role / Device Role / Timing Role: Omnipolar Hall switch provides contactless, wear-free position feedback with hysteresis to reject vibration-induced chatter.

| Clutch/Brake Pedal Position | Wiper Home Position Detection |
Use Scenario: Measures pedal travel in manual transmission clutch or brake systems via linear magnet array or rotary cam. IC Role / Device Role / Timing Role: Omnipolar switching ensures consistent activation regardless of magnet polarity orientation during assembly. Use Value: Eliminates calibration steps and reduces assembly time vs. unipolar sensors requiring precise magnet polarity alignment. | Use Scenario: Identifies wiper blade home position at end-of-travel using fixed magnet on linkage and PCB-mounted sensor. IC Role / Device Role / Timing Role: High EMC immunity and 165°C junction rating allow placement near motor housing without shielding or derating. Use Value: Achieves >99.9% first-time detection accuracy over lifetime-avoids wiper park failures that trigger warranty claims. |
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 | Unipolar South-sensing (40 G BOP), same package and micropower profile | Requires magnet with defined south-pole orientation; less tolerant of misassembly | Select when magnet polarity is strictly controlled and cost-sensitive unipolar behavior suffices. |
| TLV4913-1E | 3.3–24 V, 8 µA ICC, unipolar, SOT23-3, but no ASIL A documentation or load-dump protection | Lacks AEC-Q100 Grade 0 qualification, no integrated 40 V clamp or ISO 26262 support | Use only in non-safety-critical industrial controls where external protection is acceptable. |

FAQ
What is the magnetic sensing configuration of the APS11700LLHALT-0PL?
The APS11700LLHALT-0PL uses a planar (Z-axis) Hall-effect element sensitive to magnetic flux perpendicular to the branded face of the IC package. It is configured as an omnipolar switch with ±40 G operate point and ±22.5 G release point, enabling detection of both north and south magnetic poles without orientation dependency-making it ideal for applications like gear selectors where magnet mounting consistency is challenging.
Does the APS11700LLHALT-0PL support direct connection to a 12 V automotive battery?
Yes, the APS11700LLHALT-0PL supports direct connection to a 12 V automotive battery. Its absolute maximum supply voltage is 40 V, and it includes integrated protection against 40 V load dump transients, −18 V reverse battery, and output short-circuit events. This eliminates the need for external TVS diodes or reverse-polarity protection circuits in standard automotive installations.
What is the typical supply current consumption of the APS11700LLHALT-0PL?
The APS11700LLHALT-0PL draws a typical average supply current of 6 µA at 12 V and 25°C in micropower sleep mode. This value remains within 2–15 µA across −40°C to +85°C ambient, and increases to 11.3 µA at 150°C-enabling ultra-low-power operation in always-on vehicle subsystems such as door latch monitors or gear position sensors.
Is the APS11700LLHALT-0PL qualified for automotive use?
Yes, the APS11700LLHALT-0PL is AEC-Q100 qualified for Grade 0 (−40°C to +150°C ambient) and developed as a hardware safety element out-of-context (SEooC) with ASIL A capability per ISO 26262. It meets stringent automotive reliability, EMC, and fault-tolerance requirements-making it suitable for safety-related applications including PRNDL sensing, brake/clutch position, and wiper home detection.
What package type does the APS11700LLHALT-0PL use?
The APS11700LLHALT-0PL uses the 3-pin SOT23W surface-mount package (suffix LH), with lead (Pb)-free construction and 100% matte tin-plated leadframes. Its compact footprint and thermal resistance of 110°C/W on a 2-layer PCB support high-density automotive PCB layouts while maintaining safe junction temperatures up to 165°C.
