MOSDESIGN SEMICONDUCTOR CORP.
4-CHANNEL LED DIMMER DRIVER
LED DRIVER M1357
GENERAL DESCRIPTION
The M1357 is a monolithic, 4-channel NMOS PWM LED drivers Controller can also be directly programmed through an Serial Bus Micro-Processor Interface for applications where user defined LED pattern, color, and intensity programmability is a priority. Optimized for dimming LEDs in 256 discrete steps for Red/Green/Blue (RGB) color mixing and back light applications.
The M1357 includes an internal oscillator , four individual PWM color LED drivers and The open drain outputs directly drive the LEDs with constant sink current of 15mA per bit.
FEATURES
‧ 4 open drain outputs directly drive LEDs ‧ Constant sink current of 15mA per bit ‧ 256 brightness steps ‧ A0~A3 is External address selection.
