Melexis Technologies NV PTC04-DB-90316

Overview

PTC04-DB-90316 from Melexis is a daughter board designed to interface the PTC04 programming and test system with Melexis PTC-series position sensor ICs-including MLX90316, MLX90324, MLX90333, MLX90360, MLX90364, and MLX90365-enabling device configuration, calibration, and functional validation in lab and production environments. It provides dual-die support (Device A/B), programmable power supplies (PPS1–PPS4), analog measurement channels, and relay-based PWM signal routing.

For engineers reviewing the PTC04-DB-90316 datasheet, pinout, applications, or equivalent options, this board serves as a hardware extension for Melexis' PTC04 platform-supporting serial programming, analog stimulus/response testing, and real-time sensor characterization via its 40-pin digital and 48-pin analog connectors.

Technical Context

The PTC04-DB-90316 implements a dual-channel test interface with dedicated analog signal paths for Device A and Device B, including force/sense supply and output lines (VDDA/VDDA_Sense, OUT1A/OUT1A_Sense, etc.), four programmable power supplies (PPS1–PPS4), and four fast analog comparators (ANA.COMP0–ANA.COMP3). It integrates address decoding logic using a 74HC4052 multiplexer and eight MAX4656 high-voltage analog switches for signal routing.

It features on-board relays (Pickering 109-2-A-5/2D) for PWM mode switching on MLX90316, I²C EEPROM (PCF8582AP) for daughter board identification and lifecycle tracking, and ULN2803LW driver arrays for digital I/O expansion. All digital I/O is 5 V tolerant; analog inputs are rated up to 35 V with protection circuitry.

FAQ

What is the primary function of the PTC04-DB-90316 daughter board?

The PTC04-DB-90316 daughter board serves as a hardware interface between the Melexis PTC04 programmer and target PTC-series sensor ICs (e.g., MLX90316, MLX90364). It enables full electrical access to device pins-including force/sense lines, PWM channels, and programmable supplies-for calibration, functional testing, and serial programming in both lab and production settings. The PTC04-DB-90316 supports dual-die configurations and integrates relays and analog switches to adapt signal routing per device requirements.

Which Melexis sensor ICs are explicitly supported by the PTC04-DB-90316?

The PTC04-DB-90316 is explicitly validated for use with MLX90316, MLX90324, MLX90333, MLX90360, MLX90364, and MLX90365-six specific Melexis Triaxis® magnetic position sensor ICs. Its pinout, relay configuration (e.g., J5/J6 for MLX90316 PWM mode), and firmware-handled identification (via U2 PCF8582AP) are tailored to these devices. No support is claimed or documented for other PTC-family parts outside this list.

Does the PTC04-DB-90316 provide isolated power supplies or galvanic isolation?

No, the PTC04-DB-90316 does not provide galvanic isolation. Its +5 V digital supply, +36 V analog rail, and PPS outputs share common ground domains (DGND and AGND, tied together on board). Protection diodes (DFLR1200) and current-limiting resistors are present, but no optocouplers, isolated DC/DC converters, or transformer-based isolation are implemented. Users must ensure external system-level isolation if required for safety or noise immunity.

How does the PTC04-DB-90316 handle device identification and version control?

The PTC04-DB-90316 uses an on-board PCF8582AP I²C EEPROM (U2) to store board identity, revision (Rev. 3.0), and expiration status. During initialization, the PTC04 host reads this memory to verify compatibility and prevent use of outdated or mismatched daughter boards. This ensures firmware-level enforcement of correct hardware–software pairing-critical for reliable calibration and programming of MLX90316 and other supported devices.

Can the PTC04-DB-90316 be used without the PTC04 main programmer?

No-the PTC04-DB-90316 is not a standalone tool. It requires mechanical and electrical integration with the Melexis PTC04 main programmer board via its dual-edge connectors and relies entirely on the PTC04's microcontroller (ATmega), firmware, and host PC software for operation. It lacks independent power regulation, USB/serial interface, or embedded processing; all control signals (Rd/Wr, Port E, SCL/SDA) originate from the PTC04 host. The PTC04-DB-90316 functions solely as an extension module.
