TLC5946PWP

产品概述

The TLC5946PWP is a 16-channel 12-bit PWM LED Driver with 6-bit dot correction. Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 64 constant current sink steps for dot correction. The dot correction adjusts the brightness variations between LEDs. Both greyscale control and dot correction are accessible via a serial interface. The maximum current value of all 16 channels can be set by a single external resistor. The device power dissipation must be below the power dissipation rate of the device package to ensure correct operation. The TLC5946 has a flexible serial interface that can be connected to microcontrollers or digital signal processors in various ways.
