BD26503GUL - Dot Matrix LED Display Driver

Description

BD26503GUL is “Matrix LED Driver” that is the most suitable for the cellular phone.

It can control 7x17(119 dot) LED Matrix by internal 7-channel PMOS SWs and 17-channel LED drivers.

It can control the luminance and firefly lighting of the LED matrix by the setting of the internal register.

Features

  • LED Matrix driver (7x17) It has 7-channel PMOS SWs and 17-channel current drivers with 1/7 timing driven sequentially. Put ON/OFF(for every dot). The current drivers can drive 0-20.00mA current with 16 step(for every dot). 64 steps of the luminance control by PWM (common setting for all dots) Continuous (TDMA off ) lighting function for LED14-LED17 Easy register settin.
