BD26502GUL Dot Matrix LED Driver (7x17)

Easily enable colourful illumination and information display

BD26502GUL is a Matrix LED Driver, that can control 7x17 (119 dots) LED Matrices by internal 7-channel PMOS high side switch and 17 channel constant current circuit. Together with the integrated division control circuit and the pattern generator this enables the user to do an easy configuration of a text, character or illumination display without increasing the load of the microcontroller, connected via SPI or I2C interface. With BD26502 it is fast and easy to integrate information and illumination functionality to mobile phones, home appliances and other consumer devices.

The built-in 13-pattern generator with slope function significantly reduces the load of the microcontroller. All dots can be selected randomly. It is compatible with both single- and full-color LEDs for illumination.

A more detailed pattern generation using a microcontroller is also possible. In addition, 8-way automatic scrolling (up/down/right/left/upper right/lower right/upper left/lower left) can be configured, further lightening microcontroller load. If more than 119 dots are required you can easily expand the number by using more than one driver due to its built-in synchronous function.

Only one external component (resistor) is required for setting the maximum current (unlike conventional solutions that need a reference voltage filter capacitor and oscillator frequency-setting capacitor). Together with the small package, the result is a smaller board size and more simple design.
