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

PTC

General 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.

Key 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.
