Product details

Overview

STEVAL-TLL008V1 from STMicroelectronics is a camera flash demonstration board built around the STCF04 buck-boost LED driver IC, designed to charge a SuperCapacitor and drive high-current LEDs in flash and torch modes. It supports LED forward voltages from 2.5 V to 5.0 V, delivers up to 10 A flash current (adjustable via external resistor), and features I²C interface, NTC thermal monitoring, ready/status signaling, and optional light sensor integration for smartphone or digital camera auxiliary lighting.

For engineers reviewing the STEVAL-TLL008V1 datasheet, STEVAL-TLL008V1 pinout, STEVAL-TLL008V1 application, or STEVAL-TLL008V1 equivalent, this board enables rapid validation of SuperCap-based flash power architecture, I²C-configurable LED current control, thermal-aware flash sequencing, and low-voltage battery-backed illumination systems.

Technical Context

The board implements a complete flash power subsystem using the STCF04 - a synchronous buck-boost converter with integrated gate drivers, programmable current regulation, and dedicated SuperCap charging logic. It operates across 2.7–5.5 V input, supports shutdown/monitoring/idle/flash/torch modes, and auto-activates NTC sensing during high-power output phases.

Control is fully I²C-based (7-bit address 0x60), with status register reporting fault conditions (OV, OT, UVLO), ATN pin for interrupt signaling, and READY pin indicating stable output. The schematic integrates discrete components for current sensing, voltage reference, and thermal feedback without requiring external microcontroller firmware.

Key Specifications

FAQ

What is the primary function of the STEVAL-TLL008V1 board?

The STEVAL-TLL008V1 is a demonstration board for the STCF04 LED driver IC, engineered to validate SuperCapacitor-based flash power delivery in camera modules. It provides full hardware implementation of flash/torch mode control, I²C configuration, thermal monitoring, and status signaling - eliminating need for custom PCB design during early-stage imaging system development.

Can the board drive multiple LEDs simultaneously?

Yes - the STCF04 drives LEDs in a single-string configuration, and the board supports any LED with forward voltage between 2.5 V and 5.0 V. Multiple LEDs may be connected in series only if their combined V_F stays within that range; parallel driving is not supported due to lack of per-LED current balancing circuitry.

Is the light sensor included on the board?

No - the light sensor is optional and not populated on the standard STEVAL-TLL008V1 board. The schematic includes footprint and routing for an ambient light sensor (ALS), but users must source and solder the component separately to enable automatic brightness-adaptive flash control.

Does the board support automatic NTC thermal protection?

Yes - NTC thermal monitoring is hardwired to activate automatically during flash and torch modes, independent of the NTC_ON register bit. In all other modes (shutdown, monitoring, idle), NTC must be manually enabled via I²C command to monitor temperature and trigger foldback if threshold is exceeded.
