The SN51DP is a monolithic integrated circuit featuring seven high-voltage, high-current Darlington transistor pairs. Each pair is configured as an open-collector output, capable of sinking substantial current. Internally, each Darlington pair includes suppression diodes for inductive load protection, making the IC exceptionally robust for real-world applications.
Based on technical documentation, the is a specialized LED TV Backlight Driver IC primarily manufactured by ON-BRIG . It is frequently found in LED TV mainboards such as the TP.S506.PB801 for brands like Arielli, Crown, and Felix. SN51DP Technical Overview
