Product details
Overview
ARS19200LUBATN-L from Allegro MicroSystems is a Hall-effect-based ASIL-B-compliant wheel speed sensor IC in a 2-pin SIP UB package, featuring integrated 2200 pF ceramic capacitor, true zero-speed sensing, and differential Hall element spacing of 1.75 mm for high-resolution ring magnet detection in automotive ABS systems.
For engineers reviewing the ARS19200LUBATN-L datasheet, ARS19200LUBATN-L pinout, ARS19200LUBATN-L application, or ARS19200LUBATN-L equivalent, this device delivers certified functional safety, robust magnetic signal processing across –40°C to +150°C, and low-EMI two-wire operation with ICC(LOW) power-on state.
Technical Context
The ARS19200LUBATN-L implements a self-calibrating dual-Hall architecture with temperature-compensated amplifier and offset cancellation circuitry, enabling precise differential magnetic field measurement (BSIG: 20–1200 G) and automatic signal conditioning without external components. Its BiCMOS process integrates transducers and digital controller on one die.
It operates as a synchronous two-wire current-loop sensor with ASIL-B-certified diagnostics, delivering ICC(HIGH)/ICC(LOW) output states (12–16 mA / 5.9–8.4 mA) and supporting up to 5 kHz wheel speed signals while maintaining BOP/BRP hysteresis at 60%/40% of peak-to-peak magnetic amplitude.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wheel speed sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ATS684LSN-T | Single-Hall architecture; no integrated capacitor; requires external 10 nF filter; operates up to 125°C only | Lacks ASIL-B certification and zero-speed performance below 2 rpm; suitable for non-safety-critical chassis modules | Select when cost sensitivity outweighs functional safety requirements and ambient temperature stays below 125°C |
| A19350LUBTN-L | Same UB package and pinout; identical 2200 pF integration; but rated for ASIL A only and lacks IRESET safety current | Approved for non-ABS applications such as HVAC blower speed monitoring; not qualified for brake system use | Choose only for non-safety-critical wheel speed functions where full ASIL-B diagnostics are unnecessary |
Compared with ATS684LSN-T and A19350LUBTN-L, the ARS19200LUBATN-L uniquely combines ASIL-B certification, integrated 2200 pF capacitor, and guaranteed zero-speed operation in a production-qualified 2-pin SIP package-making it the only option qualified for OEM ABS and EPB systems requiring ISO 26262 compliance.

FAQ
What is the power-on state of the ARS19200LUBATN-L?
The ARS19200LUBATN-L has an ICC(LOW) power-on state, meaning it defaults to its low-current output mode (5.9–8.4 mA) upon initial power application. This behavior is defined by the "-L" suffix and ensures predictable startup sequencing in two-wire ABS systems where current-loop initialization must avoid false triggering.
Does the ARS19200LUBATN-L require external filtering components?
No-the ARS19200LUBATN-L integrates a 2200 pF ceramic capacitor between VCC and GND inside the UB package, eliminating the need for external EMI suppression capacitors. This reduces bill-of-materials count and improves EMC performance per CISPR 25 Class 5 without compromising signal integrity or rise/fall time (≤1.5 μs).
How does the ARS19200LUBATN-L achieve ASIL-B compliance?
The ARS19200LUBATN-L achieves ASIL-B compliance through a certified safety design process including integrated diagnostics (IRESET safety current), fully synchronous digital logic with Scan and IDDQ testing, and application-proven algorithms validated for robust operation in wheel speed environments per ISO 26262 requirements.
What is the Hall element spacing in the ARS19200LUBATN-L, and why does it matter?
The ARS19200LUBATN-L features dual Hall elements spaced precisely 1.75 mm apart. This spacing is optimized for high-resolution detection of small-diameter ring magnets and fine-pitch gear teeth, enabling accurate speed measurement even with air gaps up to 2.5 mm and minimizing phase error in differential signal processing.
Can the ARS19200LUBATN-L operate reliably at 150°C ambient temperature?
Yes-the ARS19200LUBATN-L is rated for –40°C to +150°C ambient operation and has a maximum junction temperature of 165°C. With RθJA = 213°C/W, it sustains reliable operation at 150°C ambient when VCC ≤ 4.4 V (derated per power dissipation curve), making it suitable for placement near hot engine or transmission components.
