Introduction

The MAX13089EEPD+ is a 1.8V, 8-channel, low-power, low-voltage level shifter/Mux configuration, designed to control the ON/OFF output of an LED driver, as well as work as an LED dimming device. It is primarily designed to interface with a microcontroller that supports I2C serial interfaces.

Application

The MAX13089EEPD+ is ideal for displays such as light-emitting diode (LED) backlighting and keyboard backlight applications. Additionally, it is compatible with digital camera, mobile phone displays, liquid crystal displays (LCDs) and other lighting applications that require high-level reliability and energy efficiency.

Working Principle

The MAX13089EEPD+ is a level shifter/mux configuration which can input a digital signal (logic high/low) at each input, and output a digital signal (logic high/low) at each output. The digital outputs are also capable of sinking current, allowing for a more efficient control of LEDs.

The MAX13089EEPD+ is an I2C logic compatible device. It supports 3- and 4-wire serial interfaces (with the 4th dedicated to the RESET pin), allowing for up to 8 outputs to be controlled using just 2 data lines. The I2C address register allows for multiple devices to be daisy-chained together. data lines. The I2C address register allows for multiple devices to be daisy-chained together.

The MAX13089EEPD+ is a low-power device, operating with very low ground current (~100µA). It is also capable of providing accurate LED dimming, with a configurable gain (up to 1000x) across a wide range of differential voltage levels.

The MAX13089EEPD+ is an excellent choice for LED driver and LED dimmer applications, as it offers superior performance in terms of reliability, power efficiency and flexibility.
