Product details
Overview
ARS19200LUBATN-H from Allegro MicroSystems is a Hall-effect-based ASIL-B-compliant wheel speed sensor IC in a 2-pin SIP (UB) package, integrating a 2200 pF ceramic capacitor for enhanced EMC performance. It delivers true zero-speed digital sensing of ring magnets in two-wire automotive applications, with optimized 1.75 mm Hall element spacing for high-resolution small-diameter targets and ICC(HIGH) power-on state.
For engineers reviewing the ARS19200LUBATN-H datasheet, ARS19200LUBATN-H pinout, ARS19200LUBATN-H application, or ARS19200LUBATN-H equivalent, this device supports robust wheel speed sensing in ABS/ESC systems where diagnostic coverage, thermal resilience (–40°C to +150°C), and integrated EMI suppression are critical selection criteria.
Technical Context
The ARS19200LUBATN-H implements a dual-Hall-element architecture with fixed 1.75 mm pitch to generate differential analog voltage (VPROC) from rotating ring magnets or ferromagnetic gears. Its fully synchronous digital controller includes Scan and IDDQ testing, ASIL-B-certified diagnostics, and temperature-compensated amplifier/offset cancellation circuitry.
It operates as a two-wire current-loop sensor with programmable output polarity (ICC(HIGH) on power-up), supports 0–5 kHz frequency range, and features internal supply regulation with undervoltage lockout (3.6–3.95 V) and reverse supply protection (–18 V).

Equivalent & Alternatives
The following parts are listed as comparable options for similar wheel speed sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATS684LSB-T | Single-Hall architecture; no integrated capacitor; requires external 10 nF decoupling; operates up to +165°C junction but lacks ASIL-B certification | Used in non-safety-critical speed monitoring (e.g., tachometer); not qualified for ABS/ESC functional safety paths | Select when cost sensitivity outweighs ASIL-B requirement and board-level EMI filtering is acceptable |
| TLV4961-1HAL | Two-wire interface with integrated capacitor (2200 pF); ASIL-B compliant; but rated only to +125°C ambient and uses 3-pin SMD package (not SIP) | Suitable for cabin or mid-chassis locations; not rated for direct under-hood mounting near brake calipers | Select when PCB layout allows SMD placement and ambient temperature stays below +125°C |
Compared with ATS684LSB-T and TLV4961-1HAL, the ARS19200LUBATN-H uniquely combines ASIL-B compliance, true zero-speed operation, integrated 2200 pF capacitor, and +150°C ambient rating in a 2-pin SIP form factor-making it optimal for high-reliability, space-constrained, under-hood wheel speed sensing.

FAQ
What is the power-on behavior of the ARS19200LUBATN-H?
The ARS19200LUBATN-H powers up in the ICC(HIGH) state, delivering a high-current output immediately upon valid supply voltage application. This behavior is defined by the "-H" suffix and ensures deterministic initialization for safety-critical ABS/ESC controllers that require known output polarity at boot. The device maintains this state until magnetic field transitions trigger switching between ICC(HIGH) and ICC(LOW) based on sensed pole edges.
How does the ARS19200LUBATN-H achieve ASIL-B compliance?
The ARS19200LUBATN-H achieves ASIL-B compliance through an integrated diagnostic architecture including Scan and IDDQ testing, ASIL-B-certified safety current (IRESET = 1.0–3.3 mA), and fault detection logic validated per ISO 26262. Its design process follows certified safety development workflows, and diagnostics cover internal analog path integrity, regulator stability, and magnetic signal validity - all documented in the ARS19200-DS Rev. 3 safety manual.
What is the function of the integrated 2200 pF capacitor in the ARS19200LUBATN-H?
The integrated 2200 pF ceramic capacitor in the ARS19200LUBATN-H is connected internally between VCC and GND to suppress high-frequency supply noise and improve electromagnetic compatibility. It replaces external EMI filter components, reduces PCB footprint, and enhances immunity to conducted transients per CISPR 25 Class 5 - a key enabler for simplified two-wire sensor designs in electrically noisy automotive environments.
Can the ARS19200LUBATN-H sense both ring magnets and ferromagnetic gears?
Yes, the ARS19200LUBATN-H is designed to sense both radial ring magnets and ferromagnetic gear teeth. Its dual-Hall architecture with 1.75 mm pitch generates differential signals from either target type. For ferromagnetic targets, an external back-biasing magnet is required to establish the necessary field gradient, while ring magnets provide self-contained flux patterns - both configurations are validated in the ARS19200 functional description and Figure 5.
What is the maximum operating frequency supported by the ARS19200LUBATN-H?
The ARS19200LUBATN-H supports an operating frequency range of 0–5 kHz, as specified in its electrical characteristics table. This corresponds to wheel speeds exceeding 250 km/h with standard 48-tooth tone rings and accounts for worst-case slew rate (≤1.5 μs) and internal processing latency. The device maintains full accuracy and diagnostic coverage across this entire band, including at true zero speed where conventional sensors fail.
