Product Overview

The TLC5928PWPR is a 16-channel Constant Current LED Sink Driver without LED open detection. Each channel can be turned on/off by writing serial data to an internal register. The constant-current value of all 16 channels is set by a single external resistor. The TLC5928 has two error detection circuits: one for LED open detection (LOD) and one for a pre-thermal warning (PTW). LOD detects a broken or disconnected LED and LEDs shorted to GND while the constant-current output is on. PTW indicates a high temperature condition. The constant-current values are determined by an external resistor (RIREF) placed between IREF and GND. When BLANK is low, the corresponding output is turned on if the data in the on/off control data latch are '1' and remains off if the data are '0'. When BLANK is high, all outputs are forced off.
  • 16 channels, constant-current sink output with on/off control

  • LED power-supply voltage up to 17V
  • ±1% Constant-current accuracy
  • CMOS logic level I/O
  • 35MHz Data transfer rate
  • 20ns BLANK pulse width
  • Green product and no Sb/Br
