STMicroelectronics STEVAL-ILH007V1

Overview

STEVAL-ILH007V1 from STMicroelectronics is a 150 W high-intensity discharge (HID) digital ballast evaluation board based on the STLUX385A digital controller, designed to drive sodium and metal halide lamps in street lighting systems. It integrates a boost PFC stage and full-bridge inverter, delivers >92.5% efficiency, >0.996 power factor, and <10% input current THD, with PLM remote control readiness for power-line communication networks.

For engineers reviewing the STEVAL-ILH007V1 datasheet, STEVAL-ILH007V1 pinout, STEVAL-ILH007V1 application, or STEVAL-ILH007V1 equivalent, key selection considerations include its dual-stage topology, SMED-based real-time control architecture, EN55015 EMI pre-compliance, open-load/short-circuit/overtemperature protections, and DALI/UART/PLM interface support for smart lighting infrastructure.

Technical Context

The board implements a two-stage architecture: an active boost PFC stage correcting AC input current phase alignment, and a full-bridge inverter driving HID lamps using four STF13NM60N/STF26NM60N MOSFETs. The STLUX385A controller manages both stages via independently configurable SMEDs with ≤10 ns reaction time and 1.3 ns PWM resolution.

Control logic includes analog sensing of PFC zero-crossing (PFC_ZCD), peak current (IPEAK), lamp voltage (VLAMP), and auxiliary rail monitoring (3.3 V, 12 V). Communication interfaces comprise PLM (power line modulation), DALI (IEC 62386), and UART, all routed through dedicated GPIOs and level-shifting circuitry on the STLUX385A.

FAQ

Does STEVAL-ILH007V1 support DALI protocol natively?

Yes - the board includes a fully implemented DALI transceiver (U3A/U3B TS272IPT comparators, R90/R95 pull-ups, J7 12-pin DALI connector) compliant with IEC 62386-102, enabling bidirectional lamp control and status reporting without external interface hardware.

What is the role of the STLUX385A SMEDs in this board?

The STLUX385A uses three autonomous SMEDs to generate synchronized, event-triggered PWM signals for PFC gate drive (PWM4), full-bridge leg control (PWM0–PWM3), and auxiliary timing (PWM5), eliminating software loop latency and enabling sub-10 ns fault response for overcurrent and overvoltage events.

Can STEVAL-ILH007V1 operate without PLM hardware connected?

Yes - PLM functionality is optional and isolated via J4 header; the board operates in standalone mode using front-panel switches (SW1) or UART/DALI commands. All core ballast functions - PFC regulation, lamp ignition, and thermal protection - remain fully active without PLM connection.

Is the 150 W rating adjustable for lower-wattage HID lamps?

Yes - lamp power is programmable via STLUX385A firmware configuration of current sense gain (R49, R52), PFC reference voltage, and inverter switching frequency; documented tuning procedures allow safe adaptation to 70 W or 100 W metal halide lamps with recalibrated protection thresholds.
