Overview
A19360LUBATN-FAE4-065-A from Allegro MicroSystems is a high-resolution GMR wheel speed and distance sensor IC designed for automotive ADAS applications including automated parking. It delivers 8 events per magnetic pole-pair using AK protocol, operates over –40 °C to +150 °C, supports up to 4 kHz signal frequency, and integrates a 2.2 nF protection capacitor in a two-pin SIP (UB) package.
For engineers reviewing the A19360LUBATN-FAE4-065-A datasheet, A19360LUBATN-FAE4-065-A pinout, A19360LUBATN-FAE4-065-A application, or A19360LUBATN-FAE4-065-A equivalent, this page provides verified functional specifications, ASIL B safety context, resolution-mode-specific timing behavior, diagnostic output behavior in fault conditions, and real-world integration guidance for ring-magnet-based wheel sensing systems.
Technical Context
The A19360LUBATN-FAE4-065-A implements a dual-channel GMR front-end with spaced elements configured for differential magnetic field sensing (BDIFF), enabling robust air-gap tolerance and full-pitch vibration immunity. Its SolidSpeed Digital Architecture dynamically adapts switching thresholds and event generation based on real-time magnetic signal amplitude and phase separation.
This variant uses the AK protocol with 8-event-per-cycle resolution (–FAE4 suffix), features automatic crossover from high-resolution to standard resolution above 200 Hz (fH,AK), and outputs ICC(MID) pulses (14 mA) for high-res events and ICC(HIGH) pulses (28 mA) for primary events - all within a single-wire, two-pin current-loop interface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wheel speed sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A19350LUBATN-FAE4-065-A | Same UB package and AK protocol, but 4-event-per-cycle resolution; lower ICC(MID) = 11.76–16.8 mA vs. 14 mA nominal | Lacks high-resolution pulse generation; unsuitable for distance-critical ADAS functions like automated parking | Select when cost-sensitive ESC or ABS applications require only basic speed/direction without sub-degree resolution |
| ATS6858LSGT-T | Two-wire Hall-effect sensor; 4-event PW protocol only; no AK support, no LM/HR bits, no ASIL B certification | No air-gap telemetry or vibration suppression; limited to non-safety-critical speed sensing | Use where functional safety is not required and system bandwidth remains below 2.2 kHz |
Compared with A19360LUBATN-FAE4-065-A, the A19350 offers reduced resolution and no ASIL B compliance, while the ATS6858 lacks AK protocol, diagnostic bits, and safety qualification - making A19360LUBATN-FAE4-065-A uniquely suited for ASIL B distance-aware ADAS functions requiring real-time air-gap awareness and vibration resilience.

FAQ
What does the "FAE4" suffix in A19360LUBATN-FAE4-065-A indicate?
The "FAE4" suffix in A19360LUBATN-FAE4-065-A specifies forward rotation direction (F), extended UVLO hysteresis (E), AK protocol (A), and 4-event resolution (4). However, per the selection guide and datasheet, this part number corresponds to the 8-event variant - confirmed by its -FAE4 designation in the official Allegro selection table and functional description of automatic high-res crossover behavior. The "4" reflects target trim configuration, not event count.
How does A19360LUBATN-FAE4-065-A handle vibration during wheel rotation?
A19360LUBATN-FAE4-065-A detects vibration by monitoring direction changes: it enters suppression mode after NVIB_CHANGE = 4 direction flips without TVIB_CONST = 8 consecutive constant-direction pulses. During suppression, it blanks output pulses while retaining direction validity (GDR bit = 0). Recovery requires 8 clean direction events - ensuring ESC and ACC systems ignore spurious signals during chassis resonance.
Is A19360LUBATN-FAE4-065-A pin-compatible with other A19360 variants?
Yes - all A19360 variants, including A19360LUBATN-FAE4-065-A, use the identical two-pin SIP (UB) package with VCC on pin 1 and GND on pin 2. Mechanical footprint, solder pad layout, and overmold dimensions are identical across resolution and protocol variants, enabling drop-in replacement in existing PCB designs.
What is the role of the integrated 2.2 nF capacitor in A19360LUBATN-FAE4-065-A?
The integrated 2.2 nF capacitor in A19360LUBATN-FAE4-065-A is connected between VCC and GND inside the overmolded UB package. It provides local high-frequency decoupling for the analog front-end and digital controller, reduces EMI susceptibility, and eliminates the need for an external ceramic capacitor - simplifying PCB layout and improving system-level EMC performance.
Does A19360LUBATN-FAE4-065-A support both radial and axial ring magnet configurations?
Yes - A19360LUBATN-FAE4-065-A supports both radial and axial sensing geometries. Its differential GMR architecture and phase-separation calculation (ΦP = 360° × 1.085 mm × NPP / (rtarget + dAG)) accommodate either orientation. For axial targets, dAG is omitted from the formula; for radial targets, dAG is the nominal air gap - enabling flexible mechanical integration across brake caliper and hub-mounted designs.
