Product details
Overview
ARS19510LUBBTN-FSWPHUJ from Allegro MicroSystems is a two-wire, differential Hall-effect gear-tooth sensor IC with integrated back-biasing magnet and EMC protection components. It delivers true zero-speed speed and direction output via pulse-width modulation, supports full-range dynamic air gap shifts, and operates from –40 °C to 150 °C in automotive transmission environments.
For engineers reviewing the ARS19510LUBBTN-FSWPHUJ datasheet, ARS19510LUBBTN-FSWPHUJ pinout, ARS19510LUBBTN-FSWPHUJ application, or ARS19510LUBBTN-FSWPHUJ equivalent, key selection criteria include vibration immunity level (H-variant), forward/reverse rotation detection timing, pulse-width configuration (N/W), and 2-pin SIP package compatibility with high-temperature mechanical mounting constraints.
Technical Context
The ARS19510LUBBTN-FSWPHUJ integrates three Hall elements in differential pairs for robust edge-phase comparison, enabling direction discrimination independent of air gap. Its synchronous digital controller implements proprietary vibration detection algorithms-calibrating on initial target rotation rather than vibration artifacts-to suppress false direction pulses under large-amplitude mechanical disturbance.
It uses a two-wire current-loop interface with variable pulse-width output: 45 μs typical for forward rotation (F), 90 μs typical for reverse rotation (N variant), and 180 μs for wide-pulse mode (W variant). Undervoltage lockout activates at 3.6 V, and internal 22 nF capacitor (L suffix) stabilizes supply filtering for EMI resilience in harsh automotive transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4 V to 24 V - supports direct battery connection in 12 V automotive systems with headroom for load-dump transients |
| Operating Temperature | –40 °C to +150 °C - qualified for under-hood transmission control module placement |
| Pulse Width (Forward) | 38–52 μs - encodes direction while maintaining timing margin for microcontroller input capture |
| Pulse Width (Reverse, N) | 76–104 μs - distinguishes reverse rotation unambiguously from forward pulses in same protocol frame |
| Output Current Ratio | 1.9× - high/low state current ratio enables reliable detection across cable lengths and connector resistances |
| Air Gap Handling | Full range (J suffix) - maintains valid operation across installation tolerances without recalibration |
| Vibration Immunity | High (H suffix) - outputs non-directional pulses (tw(ND)) during vibration until validated constant rotation resumes |
Pinout & Package
This device is housed in a lead-free 2-pin SIP (Single In-line Package) with tin-plated leadframe, overmolded construction, and branded face orientation for consistent mechanical mounting. The package measures 18.00 mm × 4.00 mm × 1.80 mm (L × W × H) with 2.54 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Two-wire supply input - accepts 4–24 V; powers internal regulator, Hall amplifiers, and digital controller |
| 2 | GND | Return path for output current loop - forms closed two-wire interface with VCC; referenced for internal AGC and offset adjustment |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Back-Biasing Magnet | Enables self-contained operation with ferrous gear targets-no external magnet required, reducing BOM count and alignment complexity |
| Proprietary Vibration Detection | Distinguishes true rotational edges from vibration-induced signal artifacts using dual-channel phase analysis, eliminating false direction pulses |
| Automatic Gain & Offset Control | AGC and AOA circuits normalize signal amplitude and DC offset per channel during startup calibration, ensuring stable switching across air gap variation |
| EMC-Optimized Design | Meets stringent automotive transient immunity (ISO 7637-2) and radiated emissions (CISPR 25 Class 5) without external protection components |
| True Zero-Speed Operation | Outputs valid direction pulses even at standstill-enables parking gear position detection and creep-speed monitoring in EV transmissions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gear-tooth sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATS17421SM20G-T | Single-channel output; no built-in vibration suppression algorithm; requires external capacitor | Lacks direction output and advanced air gap compensation; limited to speed-only use cases | Select only when direction detection is unnecessary and cost sensitivity outweighs functional requirements |
| APS12625KMA | Three-wire interface; higher supply current (18 mA); no integrated back-bias magnet | Requires external magnet and separate power rail; less suitable for space-constrained transmission housings | Prefer when system-level EMI filtering is already implemented and directional accuracy at zero speed is not required |
Compared with ATS17421SM20G-T and APS12625KMA, the ARS19510LUBBTN-FSWPHUJ uniquely combines two-wire simplicity, integrated back-biasing, full-range air gap handling, and H-variant vibration immunity-making it the only option qualified for zero-speed direction sensing in thermally aggressive automotive gear applications.

FAQ
What is the function of the "H" suffix in ARS19510LUBBTN-FSWPHUJ?
The "H" suffix in ARS19510LUBBTN-FSWPHUJ denotes High vibration immunity mode. In this configuration, the ARS19510LUBBTN-FSWPHUJ outputs non-directional pulses (tw(ND)) during vibration events and only resumes forward/reverse pulse-width encoding after validating sustained constant-direction rotation-ensuring no false direction signals under mechanical disturbance.
Does ARS19510LUBBTN-FSWPHUJ require an external magnet?
No, the ARS19510LUBBTN-FSWPHUJ integrates a rare-earth back-biasing pellet within its overmolded package. This eliminates the need for an external magnet and enables direct mounting opposite ferrous gear teeth or ring magnets-reducing assembly steps and improving field reliability in automotive transmission applications.
What does the "J" suffix indicate in ARS19510LUBBTN-FSWPHUJ?
The "J" suffix in ARS19510LUBBTN-FSWPHUJ specifies full-range dynamic air gap handling capability. This means the ARS19510LUBBTN-FSWPHUJ maintains valid speed and direction output across the entire specified air gap variation encountered during thermal cycling, mechanical tolerance stack-up, or housing deformation in automotive gear sensing installations.
How does ARS19510LUBBTN-FSWPHUJ achieve true zero-speed operation?
The ARS19510LUBBTN-FSWPHUJ achieves true zero-speed operation through differential Hall element pairing and synchronous digital processing that detects magnetic edge transitions-even at infinitesimal angular velocities. Its patented calibration algorithm locks onto target features during startup, enabling immediate direction pulse generation upon first detectable rotation, including sub-RPM movement in EV parking gear applications.
What is the significance of the "LUB" package designation in ARS19510LUBBTN-FSWPHUJ?
The "LUB" in ARS19510LUBBTN-FSWPHUJ identifies the 2-pin SIP (Single In-line Package) with tin-plated leadframe and integrated 22 nF supply capacitor (L = 22 nF, UB = 2-pin SIP). This package enables direct PCB mounting in high-temperature zones, provides inherent EMI filtering, and supports automated assembly-critical for automotive-grade production of transmission sensors.
