BD2802GU
No.11041EAT12
●Description
The BD2802GU is a RGB LED driver specifically engineered for decoration purposes.This RGB driver incorporates lighting
patterns and illuminates without imposing any load on CPU.This RGB driver is best-suited for illumination using RGB LEDs
and decoration using monochrome LEDs.In addition, this RGB driver has been successfully miniaturized through the use of
a VCSP85H2 (2.8 mm 0.5 mm pitch) chip size package.
●Features
1) RGB LED driver (dual drivers)
- A slope control function is incorporated (allowing dual drivers to be controlled independently).
- Slope control can be implemented using the DC current.
- Two modes “continuous illumination mode” and “illumination single cycle mode” are supported.
- Independent external ON/OFF synchronizing terminals (of dual drivers) are provided.
- Multiple drivers can be used concurrently by using the I2C address change function and supporting reference clock I/O.
2) Thermal shutdown
3) I2C BUS fast mode support (maximum rate: 400 kHz)
- A device address can be changed via an external pin.
* This driver has not been designed for anti-radiation.
* This document may be altered without prior notice.
* This document does not provide for delivery.
