DESCRIPTION

· The THL3514 is a 24-channel constant current LED driver with an LVDS interface.

· It features three output groups with constant current values set by external resistors.

· Includes an embedded oscillator and PWM controller for 256-step brightness control per channel.

· Utilizes a 2-pair LVDS serial interface for high noise tolerance, high-speed, and long-distance transmission.

· Supports cascaded and multidrop connections for flexible LED driver placement and connectivity.

· Employs a simple, one-way communication protocol that is easy to control and requires minimal CPU resources.
