TLC59482 (ACTIVE)

16-Channel, 16-Bit PWM LED Driver with 6-Bit Global Brightness

 

Description

The TLC59482 is a 16-channel, constant-current sink driver. Each channel has an individually-adjustable, pulse width modulation (PWM) grayscale (GS) brightness control with 65,536 steps. All channels have a 64-step global brightness control (BC). BC adjusts brightness deviation with other LED drivers. GS and BC data are accessible via a serial interface port.

Features

  • 16 Constant-Current Sink Output Channels
  • Sink Current Capability with Max BC Data:
    • 1 mA to 35 mA (VCC ≤ 3.6 V)
    • 1 mA to 45 mA (VCC > 3.6 V)
  • Global Brightness Control (BC):
    • 6-Bit (64 Steps) with 0% to 100% Range (default is 50%)
  • LED Power-Supply Voltage: Up to 10 V
  • VCC: 3.0 V to 5.5 V
  • Constant-Current Accuracy:
    • Channel-to-Channel: ±1% (typ), ±2.5% (max)
    • Device-to-Device: ±2% (typ), ±4% (max)
  • Data Transfer Rate: 30 MHz
  • Grayscale Control Clock: 33 MHz
  • Auto Display Repeat
  • Auto Data Refresh
  • Display Timing Reset
  • Four-Channel Grouped Delay Switching to Prevent Inrush Current
  • Operating Temperature: –40°C to +85°C
