Sn51dp Datasheet Pdf [hot] Page

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.

Accessing the full PDF datasheet ensures that all operating parameters, such as the exact PWM frequency and threshold voltages for the OVP (Over-Voltage Protection) pin, are strictly followed during repair or design. SN51DP LED TV DRIVER - NETASHOP.GR

Supplies power to the IC, usually derived from the main board power supply. sn51dp datasheet pdf

Prevents damage if the LED string becomes open-circuit.

Compensation pin for error amplifier frequency loop stability. OVP The following voltage measurements were taken from a

Note: There is a separate result showing "SN5-0R1B" as a wirewound resistor by Bourns Electronic Solutions (Riedon Series). However, based on the specific "SN51DP" query, the LCD power chip description is the primary match. To get you the exact details,

The table below summarizes the essential electrical characteristics of the SN51DP. These are based on typical specifications found across various distributors: SN51DP LED TV DRIVER - NETASHOP

Use four channels to drive a unipolar stepper motor. Each phase connects to an output, with common center taps connected to the motor supply (e.g., 12V). The COM pin connects to the same supply.

When troubleshooting, first check for ~12V at Pin 1 (VIN) and a high signal (typically 3.3V) at Pin 2 (DIM).

The technical specifications found within the SN51DP datasheet include the following operational highlights: Specifications SSOP-10 / MSOP-10 (10-Pin Surface Mount) Primary Application LED/LCD Backlight Driver & DC Motor Controller Dimming Capability Standalone Digital Pulse Width Modulation (DPWM) Resolution Up to 8-bit programmable resolution Regulator Built-in On-chip 3.3V power regulator Safety Features

The Darlington pair configuration multiplies the current gain, meaning you can drive heavy loads without needing additional driver transistors or MOSFETs.
