Product details
Overview
A19530LUCCTN-FOOOOEJ-A from Allegro MicroSystems is a three-wire Hall-effect transmission speed and direction sensor IC designed for automotive gear-tooth and magnetic-wheel sensing. It delivers true zero-speed operation, ASIL B safety compliance, vibration-immune direction detection, and pulse-width encoded output (45 µs forward / 90 µs reverse typical) in a 3-pin SIP package. Used in automatic transmission control units to monitor input shaft rotation.
For engineers reviewing the A19530LUCCTN-FOOOOEJ-A datasheet, A19530LUCCTN-FOOOOEJ-A pinout, A19530LUCCTN-FOOOOEJ-A application, or A19530LUCCTN-FOOOOEJ-A equivalent, this page provides verified technical context, calibrated vibration-detection behavior, ASIL B diagnostic timing (5 ms safe-state duration), air-gap-independent switch points, and confirmed -FOOOOEJ-A configuration features including forward-direction pulses, speed-only fallback, open/short diagnostics, and ASIL protocol enablement.
Technical Context
The A19530LUCCTN-FOOOOEJ-A integrates dual differential Hall channels with automatic gain control (AGC) and automatic offset adjustment (AOA) to normalize signal amplitude across variable air gaps. Its synchronous digital controller implements patented algorithms that distinguish true target rotation from angular vibration by calibrating on initial tooth transitions-not vibration artifacts-ensuring accurate direction pulses in running mode.
This variant uses the -FOOOOEJ-A configuration: forward-direction pulse emission (pin 1 → pin 3), speed-only output mode (-O), no vibration immunity (-O), open/short diagnostic enabled (-E), narrow reverse pulse width (-N), single-pulse-per-tooth-valley (-S), and ASIL protocol active (-A). It outputs only speed information via pulse rate (0–12 kHz max), with no direction pulses under vibration or during calibration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar speed-sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A19350LUCCTN-FOOOOEJ-A | Lacks ASIL B certification; no integrated diagnostics; same -FOOOO speed-only output format | Suitable for non-safety-critical speed monitoring (e.g., HVAC blower feedback), not for transmission control | Select when ASIL compliance is unnecessary and cost sensitivity outweighs diagnostic coverage. |
| ATS612LSGT-T | Two-wire current-output interface; no ASIL B; lower temperature rating (−40 °C to +125 °C); no open/short diagnostics | Designed for engine crankshaft/camshaft sensing; lacks speed-only mode flexibility and integrated capacitors | Choose for legacy two-wire architectures where wiring simplicity outweighs diagnostic depth and thermal margin. |
Compared with A19530LUCCTN-FOOOOEJ-A, the A19350 offers identical speed-only functionality but omits ASIL B design assurance and diagnostic self-test, while the ATS612 requires external current-loop support and sacrifices 25 °C of operating margin-making the A19530LUCCTN-FOOOOEJ-A the only option meeting full ASIL B, zero-speed, and integrated EMC requirements in one package.

FAQ
What is the output protocol of the A19530LUCCTN-FOOOOEJ-A?
The A19530LUCCTN-FOOOOEJ-A uses a speed-only pulse-width output protocol: it generates a pulse train whose frequency corresponds to target rotational speed (0–12 kHz), with no direction pulses. This is defined by its -FOOOO configuration suffix. The device does not output tw(FWD) or tw(REV) pulses; instead, it delivers consistent timing aligned to magnetic edge transitions, supporting applications where direction is irrelevant or derived elsewhere. Pulse width remains fixed per configuration - here, narrow reverse width (-N) applies only if direction were enabled, but in -FOOOO mode, only speed pulses occur.
Does the A19530LUCCTN-FOOOOEJ-A support true zero-speed operation?
Yes, the A19530LUCCTN-FOOOOEJ-A supports true zero-speed operation: it produces valid output pulses even when the target is stationary or rotating below 1 rpm. This capability stems from its differential Hall architecture and adaptive signal processing, which detect minute magnetic field changes without requiring motion-induced dV/dt. In speed-only mode (-FOOOO), the first pulse occurs within 2 ms of power-on (tPO ≤ 2 ms), enabling immediate position verification at standstill - critical for parking gear detection and hybrid mode engagement in the A19530LUCCTN-FOOOOEJ-A.
How does the ASIL B compliance of the A19530LUCCTN-FOOOOEJ-A function in practice?
The A19530LUCCTN-FOOOOEJ-A implements ASIL B compliance as a hardware safety element out-of-context (SEooC) per ISO 26262. It continuously monitors internal signal chain integrity and output voltage levels. Upon detecting a fault (e.g., open/short on VCC, GND, or OUT), it drives the output to a safe low state (<180 mV) for exactly 5 ms (tw(ASIL_safe)), then attempts self-reset. This behavior is fully autonomous and requires no host MCU intervention - a key design feature of the A19530LUCCTN-FOOOOEJ-A's certified safety architecture.
What diagnostic capabilities does the A19530LUCCTN-FOOOOEJ-A provide?
The A19530LUCCTN-FOOOOEJ-A provides open/short diagnostic capability enabled by its -E suffix. It detects hard shorts (VCC–GND, VCC–OUT, OUT–GND) and open circuits (open VCC, open OUT, open GND) by analyzing output voltage levels relative to VPU. Faults trigger the ASIL-safe low output (<180 mV) for 5 ms, after which the device self-resets. Unlike basic variants, the A19530LUCCTN-FOOOOEJ-A performs this diagnostics passively - no additional pins, commands, or timing windows are required beyond standard three-wire operation.
Is the A19530LUCCTN-FOOOOEJ-A pin-compatible with other A19530 variants?
Yes, all A19530 variants - including the A19530LUCCTN-FOOOOEJ-A - share identical 3-pin SIP (UC) packaging and pinout (VCC, GND, OUT), ensuring mechanical and electrical compatibility across configurations. However, functional behavior differs significantly: the A19530LUCCTN-FOOOOEJ-A operates in speed-only mode with ASIL diagnostics enabled, whereas variants like A19530LUCCTN-FSIBCEJ-A deliver direction pulses and use different vibration-immunity algorithms. No PCB layout change is needed when substituting within the A19530 family, but firmware and system-level interpretation must align with the selected configuration.
