Product details
Overview
A19530LUCCTN-FSIBCEJ-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-compliant diagnostics, and programmable pulse-width output encoding speed and direction. Its 3-pin SIP package supports ring-magnet or ferrous-target applications in automatic transmission control systems.
For engineers reviewing the A19530LUCCTN-FSIBCEJ-A datasheet, A19530LUCCTN-FSIBCEJ-A pinout, A19530LUCCTN-FSIBCEJ-A application, or A19530LUCCTN-FSIBCEJ-A equivalent, key selection considerations include vibration-immunity mode (H), open/short diagnostic enable (E), ASIL protocol activation (A), reverse/non-direction pulse width (N), dual-pulse output (D), forward rotation polarity (F), and high-temperature operation up to 150 °C.
Technical Context
The A19530LUCCTN-FSIBCEJ-A integrates two differential Hall channels with AGC and AOA circuitry to normalize signal amplitude across air-gap variations and compensate for chip/magnet offsets. Its synchronous digital controller implements patented algorithms for vibration detection and direction validation during running mode.
It uses a variable pulse-width protocol where forward rotation yields ~45 µs pulses, reverse yields ~90 µs (N-suffix), and non-direction pulses are suppressed under high-vibration conditions (H-mode). The device supports dual-pulse output (one per tooth and valley) and includes integrated 220 nF and 4.7 nF EMC capacitors in a single overmolded package.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Hall-effect transmission speed and direction sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| A19350LUCCTN-FSIBCEJ-A | Lacks dual-pulse (D) output; supports only single-pulse (S) mode - lower resolution per revolution | Suitable for cost-sensitive applications where tooth-valley discrimination is unnecessary | Select when system design does not require per-tooth-and-valley timing granularity |
| ATS616LSGT-T | No ASIL B certification; no integrated open/short diagnostics; fixed pulse-width protocol without H-mode vibration immunity | Applicable in non-safety-critical industrial gear sensing where functional safety is not mandated | Choose only for legacy designs lacking ISO 26262 requirements and where diagnostic coverage is handled externally |
Compared with A19530LUCCTN-FSIBCEJ-A, the A19350 variant trades dual-pulse resolution for reduced complexity and cost, while the ATS616LSGT-T omits ASIL compliance and embedded diagnostics-making both unsuitable as drop-in replacements in safety-critical automotive transmission control.

FAQ
What is the function of the 'H' suffix in A19530LUCCTN-FSIBCEJ-A?
The 'H' in A19530LUCCTN-FSIBCEJ-A denotes High vibration immunity mode. In this configuration, the A19530LUCCTN-FSIBCEJ-A suppresses direction pulses during angular vibration while preserving maximum air-gap capability. It outputs non-direction pulses (tw(ND)) until validated direction data is confirmed upon stable rotation, ensuring reliable operation in high-shock transmission environments.
Does A19530LUCCTN-FSIBCEJ-A support true zero-speed sensing?
Yes, A19530LUCCTN-FSIBCEJ-A supports true zero-speed operation. Its differential Hall architecture and adaptive signal processing allow it to detect and encode direction even when the target is stationary or rotating extremely slowly. This capability is confirmed in the datasheet's PERFORMANCE CHARACTERISTICS table and is essential for parking gear engagement and creep control in modern automatic transmissions.
How does the ASIL B compliance of A19530LUCCTN-FSIBCEJ-A impact system integration?
A19530LUCCTN-FSIBCEJ-A is certified as an ASIL B safety element out-of-context (SEooC) per ISO 26262. When integrated per Allegro's safety manual, it provides certified diagnostic coverage-including scan path, IDDQ measurement, and ASIL-safe output states-reducing the safety case burden on the host ECU. This allows A19530LUCCTN-FSIBCEJ-A to serve as a standalone safety-critical sensor in transmission control units without requiring redundant hardware.
What is the significance of the 'D' and 'N' characters in A19530LUCCTN-FSIBCEJ-A?
The 'D' indicates Dual-pulse output mode (one pulse per tooth and one per valley), doubling timing resolution versus single-pulse variants. The 'N' specifies Reverse pulse width = 90 µs and Non-direction pulse width = 180 µs (narrow). Together, these configure A19530LUCCTN-FSIBCEJ-A for high-fidelity direction discrimination with minimal pulse overlap in fast-rotating transmission applications.
Can A19530LUCCTN-FSIBCEJ-A operate reliably at 150 °C ambient temperature?
Yes, A19530LUCCTN-FSIBCEJ-A is fully specified for continuous operation at −40 to +150 °C ambient temperature. Its junction temperature limit is 165 °C, and thermal derating guidance is provided in the datasheet. The device has been qualified per AEC-Q100 Grade 0 standards, confirming its suitability for under-hood automotive transmission control applications where sustained high-temperature exposure occurs.
