PT16940 - Serial-In Parallel-Out 12CH LED Driver

Datasheet Summary

Description

The PT16940 is a serial-in parallel-out controlled LED driver with 35V output voltage rating.

With the input of 3-line serial data, it turns the 12ch open drain output on/off.

Due to its compact size, it is optimal for small space.

Features

  • Open Drain Output.
  • 3-line Serial Control + Enable Signal.
  • Cascade Connection Compatible.
  • TSSOP-20 Package.
  • Internal 12ch Power Transistor.
  • Output Slew Rate Typical 20V/μs (for Low EMC Noise) BLOCK.
