MAX6965ATE+ (MAXIM INTEGRATED PRODUCTS)

The MAX6965ATE+ is a 9-output LED driver with intensity control and hot insertion protection in 16 pin TQFN package. This I2C compatible serial interfaced peripheral device provides microprocessors with nine additional output ports. All outputs are capable of driving LEDs or providing logic outputs with external resistive pull-up up to 7V. An 8bit PWM current control is also integrated. Four of the bits are global control and apply to all LED outputs to provide coarse adjustment of current from fully off to fully on with 14 intensity steps. Additionally each output then has an individual 4bit control which further divides globally set current into 16 more steps. Each output has independent blink timing with two blink phases. The SDA, SCL, active-low RST, BLINK and slave address input AD0 remain high impedance in power-down (V+ = 0V) with up to 6V asserted upon them. It is used in LCD backlights, LED status indication, keypad backlights and RGB LED drivers.
