What is the exact of the television or control board you are repairing?
But what exactly is the SN51DP? Why is its datasheet so sought after? And more importantly, how do you read it to extract the vital information you need? This long-form article will serve as your complete guide—from locating the genuine PDF to understanding every graph, table, and absolute maximum rating inside.
Used extensively as the driver cornerstone in budget-to-midrange 32-inch to 55-inch LED TVs .
Let us assume you have secured the . Now, what do all those numbers mean? Here is your guided tour. sn51dp datasheet pdf
to verify if the IC itself is still operational, though this is only recommended for diagnostic purposes.
The SN51DP is a dual H-bridge motor driver IC, capable of driving two DC motors or one stepper motor. It is designed to operate at high voltages (up to 36 V) and currents (up to 2.5 A per H-bridge). The IC features a high-performance MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) architecture, which provides high efficiency, low power dissipation, and high reliability.
The is a specialized power management integrated circuit (IC) primarily used as a high-brightness LED driver for LCD TV backlighting. Manufactured by ON-BRIG , it is commonly found on mainboards such as the TP.S506.PB801 used in television brands like Arielli, Crown, Felix, and Cyberlux. Key Technical Specifications What is the exact of the television or
The (frequently cross-referenced as SN510P ) is a highly specialized, 10-pin power management and LED backlight driver integrated circuit (IC) primarily packaged in an SSOP-10 or MSOP-10 format. Widely integrated into modern Liquid Crystal Display (LCD) hardware, television control boards, and multi-purpose flat-panel monitors, this component serves as the core regulator for driving high-brightness LED arrays.
The device comes in a small surface-mount package, typically identified as a or MSOP-10 .
It is RoHS compliant , meeting modern safety and environmental standards. Practical Verdict And more importantly, how do you read it
The SN51DP is a specialized primarily found in the backlight drive circuits of LED-LCD televisions and display panels. Its main job is to take a lower DC voltage (typically 12V or 24V) from the power supply and efficiently boost it to the higher voltages needed to power the strings of LEDs that illuminate the screen from behind.
The following voltage measurements were taken from a working SN51DP in a PPTV 40C2 power supply board . These readings can be valuable references for diagnosing a non-functional backlight.
: Checking the components connected to the FB (Feedback) and CS (Current Sense) pins to ensure the IC is receiving accurate data regarding the circuit's status. Technical Documentation & Resources
Feedback input pin; reads voltage drops from the LED cathode string to maintain constant current regulation.
