Sn51dp Datasheet __hot__ Jun 2026
Engineered to minimize energy consumption, crucial for power-saving, modern display devices.
The SN51DP consists of a differential driver and a differential receiver. The driver section converts a single-ended input signal into a balanced differential signal, while the receiver section converts the balanced differential signal back into a single-ended output signal.
Furthermore, the SN51DP features robust internal protection circuitry, including and Open-LED protection . If an LED in the string burns out or a component failure causes a dangerous voltage spike, the IC immediately shuts down the backlight drive to prevent cascading damage to the power supply or the display panel. Troubleshooting Common SN51DP Failures

The SN51DP is manufactured by various suppliers, with being a primary source for the chip. However, due to its application in widely manufactured consumer electronics, the IC is distributed by multiple global semiconductor vendors. The chip is typically offered in a 10-pin TSSOP (Thin Shrink Small Outline Package) or 10-pin SSOP (Shrink Small Outline Package) form factor, both of which are surface-mount packages designed for compact, automated assembly lines. The "MSOP-10" or "SSOP-10" designation is critical for engineers designing printed circuit boards (PCBs), as it dictates the exact land pattern and soldering profile required during manufacturing.
This technical deep-dive breaks down the SN51DP datasheet specifications, pin configuration, circuit implementation, and troubleshooting methods for display technicians. Technical Specifications Overview The IC Sn51dp schematic

The SN51DP is available in an 8-pin SOIC package. The pin configuration is as follows:
Most SN51DP datasheets include:
The SN51DP is a specialized, cost-effective workhorse that powers the backlights of countless LCD televisions. While official manufacturer datasheets are difficult to locate due to its nature as a generic component, the collective knowledge of the TV repair community has mapped out its core functions and failure modes.
The (frequently cross-referenced as the SN510P ) is a highly specialized, 10-pin power management integrated circuit (IC) primarily deployed as a Pulse Width Modulation (PWM) controlled LED backlight driver . Commonly manufactured by ON-BRIG, this surface-mount chip is widely integrated into the power supply and inverter sections of flat-screen LCD/LED televisions, desktop monitors, and industrial display modules. It stabilizes current delivery to backlight strips to prevent flickering and screen blackouts. Technicians and electronics design engineers sourcing the SN51DP datasheet typically encounter it when resolving "no backlight" conditions or modifying driver board circuit boards.
