Allegro MicroSystems ASEK-ATS343-ATS344-KIT-T-DK

Overview

ASEK-ATS343-ATS344-KIT-T-DK from Allegro MicroSystems is a development kit for evaluating the ATS344 high-precision, back-biased programmable Hall-effect linear sensor IC and its predecessor ATS343. It supports two-wire current-mode PWM output, factory-calibrated differential magnetic sensing with integrated SmCo rare-earth pellet, and full EEPROM-based configuration of bandwidth (250–4000 Hz), sensitivity multiplier (0–8×), quiescent output offset (±50% FSO), and dual-segment temperature compensation. Designed for axial position sensing of rotating ferromagnetic targets in automotive transmission and engine timing systems.

For engineers reviewing the ASEK-ATS343-ATS344-KIT-T-DK datasheet, ASEK-ATS343-ATS344-KIT-T-DK pinout, ASEK-ATS343-ATS344-KIT-T-DK application, or ASEK-ATS343-ATS344-KIT-T-DK equivalent, this kit enables rapid validation of magnetic target geometry, air gap tolerance, PWM duty-cycle linearity, and customer-programmable parameter tuning-including 1st/2nd-order sensitivity TC, magnetic offset TC, and output clamps-under real-world thermal and supply-voltage conditions.

Technical Context

The ASEK-ATS343-ATS344-KIT-T-DK provides hardware and firmware infrastructure to configure and test the ATS344's digital signal processing chain, including 12-bit ADC, proprietary four-phase chopper stabilization, dynamic offset cancellation, and active stress compensation circuitry. It interfaces directly with the ATS344's single-wire Manchester-encoded serial programming interface via VCC modulation and ICC response.

This kit supports full characterization of the ATS344's programmable features: 3-bit bandwidth selection, 12-bit fine quiescent output adjustment (QVODC), 12-bit sensitivity control (SENSDC), 8/9-bit temperature coefficient parameters (TC1_SENS_CLD/HOT, TC2_SENS_CLD/HOT), and 11-bit output clamp settings (CLAMP_HIGH/LOW), all stored in on-chip EEPROM with ECC error correction.

FAQ

What is the primary function of the ASEK-ATS343-ATS344-KIT-T-DK?

The ASEK-ATS343-ATS344-KIT-T-DK is an evaluation kit designed exclusively for the ATS343 and ATS344 programmable Hall-effect linear sensor ICs. It enables engineers to configure, validate, and characterize key device parameters-including bandwidth, sensitivity, temperature compensation coefficients, and output clamps-using the ATS344's built-in EEPROM and Manchester-encoded serial interface. The kit includes reference target geometry and software tools to verify axial position sensing performance under real operating conditions.

Does the ASEK-ATS343-ATS344-KIT-T-DK support both ATS343 and ATS344 devices?

Yes, the ASEK-ATS343-ATS344-KIT-T-DK is explicitly designed to support both the ATS343 and ATS344 linear Hall-effect sensor ICs. Its hardware interface, firmware, and documentation accommodate differences in programmable parameter sets and EEPROM memory maps between the two parts while maintaining consistent evaluation workflows for magnetic target calibration, PWM output linearity, and thermal drift validation.

Can the ASEK-ATS343-ATS344-KIT-T-DK program the ATS344's EEPROM in-system?

Yes, the ASEK-ATS343-ATS344-KIT-T-DK fully supports in-system programming of the ATS344's EEPROM via its dedicated Manchester-encoded serial interface. It allows writing and reading of all customer-programmable parameters-including bandwidth (F3DB_DC), sensitivity multiplier (SENSDC), quiescent output offset (QVODC), temperature compensation coefficients (TC1_SENS_CLD/HOT, TC2_SENS_CLD/HOT), and output clamps (CLAMP_HIGH/LOW)-with ECC-protected transactions and access code authentication as defined in the ATS344 datasheet.

What magnetic target configurations can be validated using the ASEK-ATS343-ATS344-KIT-T-DK?

The ASEK-ATS343-ATS344-KIT-T-DK supports validation against the official Allegro reference target-a V-groove machined on 1018 CRS mild steel with nickel plating-as specified in Figures 2 and 3 of the ATS344 datasheet. It enables measurement of differential magnetic input signal versus centerline displacement across defined air gaps (e.g., 1.75–7 mm), allowing users to correlate ATS344 PWM output duty cycle to axial target position and verify linearity error (< ±2% FSO) and effective resolution (up to 9 bits).

Is the ASEK-ATS343-ATS344-KIT-T-DK qualified for automotive applications?

Yes, the ASEK-ATS343-ATS344-KIT-T-DK is intended for use with the AEC-Q100 Grade 0 qualified ATS344 sensor IC. While the kit itself is not certified, it provides the complete evaluation environment required to validate ATS344 performance under automotive-grade conditions-including operation from –40°C to 150°C, supply voltage cycling (3.75–9.5 V), and thermal stress profiling per AEC-Q100 requirements-ensuring readiness for integration into transmission position sensors, camshaft sensors, and other safety-critical automotive subsystems.
