TLC5958 datasheet



The TLC5958 is a 48 channels constant-current sink driver for multiplexing system with 1 to 32 duty ratio. Each channel has an individually-adjustable, 65536-step, pulse width modulation (PWM) grayscale (GS).

48K bit display memory is implemented to increase the visual refresh rate and to decrease the GS data writing frequency. The output channels are grouped into three groups, each group has 16 channels. Each group has a 512-step color brightness control (CC) function. The maximum current value of all 48 channels can be set by 8-step global brightness control (BC) function. CC and BC can be used to adjust the brightness deviation between LED drivers. GS, CC, and BC data are accessible via a serial interface port.


1. 48 Channels Constant Current Sink Output

3. Global Brightness Control (BC) : 3-Bit (8 Step)
4. Color Brightness Control (CC) for Each Color Group: 9-Bit (512 Step), Three Groups
5. Grayscale(GS) Control with Multiplexed Enhanced Spectrum(ES) PWM: 16bit
6. 48K bit Grayscale Data Memory Support 32-multiplexing
7. LED Power Supply Voltage Up To 10V
