Product details
Overview
A19530LUCC-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, 45 µs forward pulse width, 90 µs reverse pulse width (N-variant), and integrated diagnostics with open/short detection. It serves in automatic transmission position and speed feedback systems.
For engineers reviewing the A19530LUCC-FOOOOEJ-A datasheet, A19530LUCC-FOOOOEJ-A pinout, A19530LUCC-FOOOOEJ-A application, or A19530LUCC-FOOOOEJ-A equivalent, key selection considerations include ASIL B protocol support, high-vibration immunity (H-variant), pulse-width-based direction encoding, and diagnostic-safe-state timing (5 ms).
Technical Context
The A19530LUCC-FOOOOEJ-A integrates dual differential Hall channels, AGC and AOA circuitry, and a synchronous digital controller to extract rotation direction and speed from ferrous targets or ring magnets. Its patented vibration-detection algorithm calibrates using initial true rotation teeth-not vibration artifacts-ensuring accurate running-mode output.
It implements a three-wire pulse-width modulation protocol where forward rotation yields ~45 µs pulses, reverse yields ~90 µs (N-variant), and non-direction pulses are 180 µs wide. The -H suffix enables high vibration immunity: direction pulses are suppressed during angular vibration while preserving maximum air-gap capability (up to 1500 G differential field).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect speed and direction sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A19350LUCCTN-FSIBCEJ-A | Lower max frequency (6 kHz vs. 12 kHz), no ASIL B certification, lacks integrated EMC capacitors | Suitable for non-safety-critical industrial gear sensing but not automotive ASIL B systems | Select only if ASIL compliance and full-temperature-range vibration immunity are not required |
| ATS6858LSGT-T | Two-wire current-output interface, no pulse-width direction encoding, lower max differential field (1000 G) | Designed for cost-sensitive ABS wheel speed applications; lacks programmable vibration immunity modes | Choose for legacy two-wire systems where direction resolution is secondary to simplicity and cost |
Compared with A19350LUCCTN-FSIBCEJ-A and ATS6858LSGT-T, the A19530LUCC-FOOOOEJ-A uniquely combines ASIL B compliance, high-vibration immunity (–H), integrated EMC filtering, and true zero-speed direction detection in a single three-wire package-making it the only option qualified for next-generation transmission control safety architectures.

FAQ
What is the ASIL B safety qualification scope for A19530LUCC-FOOOOEJ-A?
The A19530LUCC-FOOOOEJ-A is certified as a hardware safety element out-of-context (SEooC) per ISO 26262 for ASIL B. This means its internal design-including diagnostics, scan path, IDDQ testing, and fault response-is validated to meet ASIL B requirements when integrated and used per the safety manual. The A19530LUCC-FOOOOEJ-A does not achieve ASIL B alone; system-level integration per specified constraints is required to claim ASIL B functionality.
How does the –H vibration immunity mode affect direction pulse generation in A19530LUCC-FOOOOEJ-A?
In the A19530LUCC-FOOOOEJ-A's –H (high vibration immunity) mode, direction pulses are suppressed during angular vibration events, emitting only non-direction pulses (tw(ND) = 180 µs) until validated constant rotation resumes. This prevents false direction toggling while maintaining full air-gap capability (up to 1500 G). Unlike –C or –L variants, the A19530LUCC-FOOOOEJ-A does not emit continuous direction pulses under vibration.
What are the exact pulse width values for forward and reverse rotation in A19530LUCC-FOOOOEJ-A?
The A19530LUCC-FOOOOEJ-A uses the –N suffix for reverse pulse width, specifying tw(FWD) = 38–52 µs (typ. 45 µs) and tw(REV) = 76–104 µs (typ. 90 µs). These values are measured from falling to rising edge transitions and remain stable across −40 °C to +150 °C. The A19530LUCC-FOOOOEJ-A does not support intermediate or wide variants-the N-variant is fixed per its part number.
Does A19530LUCC-FOOOOEJ-A require external pull-up resistors, and what value is recommended?
Yes, A19530LUCC-FOOOOEJ-A requires an external pull-up resistor on the OUT pin. For open/short diagnostic operation (enabled by –E suffix), Allegro specifies RPU = 1.45–3.4 kΩ. At 5 V pull-up, the A19530LUCC-FOOOOEJ-A guarantees Vdiag-Low ≤ 1250 mV and Vdiag-High ≥ 3750 mV. Using values outside this range invalidates diagnostic accuracy and may cause false fault reporting.
Can A19530LUCC-FOOOOEJ-A operate with both ring magnets and ferrous gear teeth?
Yes, A19530LUCC-FOOOOEJ-A supports both ring-magnet and ferrous-target sensing. With ring magnets, it operates in differential mode (Channels A/B); with ferrous gears, it requires back-biasing with an external magnet to generate sufficient differential field (30–1500 G). The A19530LUCC-FOOOOEJ-A's AGC and AOA circuits automatically adapt to either configuration without recalibration.
