The SY77782 8-channel LED driver integrates 30V current sinks capable of delivering up to 60mA of continuous output current and 120mA peak current. It provides flexible LED brightness control through 10-bit local analog dimming and 16-bit local pulse-width modulation (PWM) dimming. The SY77782 offers a 1-wire interface for flexible control. An internal 34.5MHz clock controls the LED current using a PWM signal ranging from 2.81kHz to 33.69kHz.

Built-in protections such as LED short, LED open and over-temperature are provided to ensure reliable operation.

The SY77782 is available in a compact QFN2x2-14 package, with an optimized pinout designed  to support single-layer PCB design.
