The in liquid crystal display (LCD) applications. Commonly manufactured by ON-Brig and engineered in a compact 10-pin package (SSOP-10 or MSOP-10), this specialized controller regulates current delivery to LED strips within modern television panels. It is widely found on standard Chinese mainboards (such as the TP.S506.PB801) used by consumer TV brands like Arielli, Crown, and Felix.
Each channel exhibits a high DC current gain (hFE) typically exceeding 1000 at 350 mA, allowing a microcontroller pin (sourcing only 1–2 mA) to switch a 500 mA load effortlessly.
This table is split into two columns: Min, Typ, Max. As a designer, always design to the Min and Max values—never the Typical.
If the LED string breaks or opens, the voltage will spike. The OVP pin detects this and shuts down the gate drive to protect the components. Common Issue: Protection Mode
