DESCRIPTION

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

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

· The 2-pair LVDS serial interface supports high-speed, long-distance, and noise-tolerant communication.

· It allows cascaded and multidrop connections, offering design flexibility.

· The simple one-way communication protocol is easy to control and requires minimal CPU resources.

FEATURES

· 24 constant current output channels with up to 40mA/ch and 40V output voltage.

· Individual 256-step brightness control and output disable/enable functionality.

· 2-pair LVDS or 3-wire CMOS serial input up to 10Mbps.

· Bridge function for converting 3-wire CMOS to 2-pair LVDS output.

· Repeater function with waveform and timing correction for LVDS input/output.

· Supports up to 62 device addresses and general call functionality.

· Protection circuits include UVLO, short circuit protection, and thermal shutdown.

· Operates at a supply voltage of 3.0~5.5V in a QFN 48-pin exposed pad package.

· Compliant with EU RoHS standards.

APPLICATIONS

· Amusement lighting.

· LED backlighting.

· LED displays.
