Overview
The BD2802GU-E2 is a dual-channel RGB constant current LED driver IC designed for illumination applications. It operates within an input voltage range of 2.7 V to 5.5 V and supports a switching frequency of 1 MHz. The device provides six outputs with a maximum output current of 30.48 mA per channel and 182 mA total. It features I²C interface support up to 400 kHz, 128-step DC dimming, and slope control functions. The component includes thermal shutdown protection and is housed in a VCSP85H2-24 package.
Feature Summary
- Dual-channel architecture supporting independent slope control for each driver via DC current adjustment.
- Integrated continuous illumination mode and single-cycle illumination mode to reduce CPU processing load.
- Supports I²C fast mode communication with configurable device addresses via external pins.
- Includes thermal shutdown circuitry and independent external ON/OFF synchronizing terminals.
Applications
- Decorative lighting systems utilizing RGB LEDs
- Single-color LED decoration circuits
- Illumination devices requiring reduced host processor overhead
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm that the VCSP85H2-24 package dimensions align with your PCB footprint requirements. Ensure the I²C address configuration matches your system design, as it can be modified via external pins. Validate that the operating temperature range meets your environmental specifications.
Selection Notes
Select this component when designing low-profile RGB lighting solutions that require precise constant current regulation without heavy microcontroller intervention. The integrated illumination modes simplify firmware development by handling basic lighting sequences internally. Consider the 1 MHz switching frequency for efficient passive component selection. Verify that the 30.48 mA per channel limit suffices for the target LED forward current requirements.
Part Context
This part belongs to ROHM Semiconductor's RGB constant current LED driver series, specifically engineered for decorative and general illumination markets. It distinguishes itself from charge pump variants by utilizing a buck/boost topology suitable for direct battery or low-voltage supply operation. The family emphasizes ease of integration through built-in timing and synchronization features.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official cross-reference guide for verified alternatives.
