| Parameter | Min | Typ | Max | Unit | |----------------------------|-------|-------|-------|------| | Supply Voltage (Load) | 0 | 24 | 50 | V | | Output Current (per pin) | 0 | 350 | 500 | mA | | Input Voltage (Logic High) | 3.0 | 5.0 | 24 | V | | Input Voltage (Logic Low) | 0 | 0.8 | 1.0 | V | | Input Current (ON) | 0.55 | 1.0 | 1.85 | mA | | Input Current (OFF) | 0 | 0 | 50 | µA |

While a direct, detailed PDF datasheet was not extracted, the function as an "LCD power chip" implies standard functionalities related to powering liquid crystal displays.

During complex television or monitor repair sessions, technicians often face a dilemma: the TV turns on momentarily, the backlight flashes, and the display immediately goes black. This symptom usually signals that the via its internal Over-Voltage Protection (OVP) or feedback loop failure.

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.

: Standalone digital pulse width modulator (DPWM) / LED driver. Package Type : SSOP-10 (10-pin) or MSOP-10. Operating Voltage Range : Temperature Range : -20∘Cnegative 20 raised to the composed with power C +130∘Cpositive 130 raised to the composed with power C

This configuration is a standard topology, which takes a lower input voltage (e.g., 12V) and "boosts" it up to the required backlight voltage (e.g., 71V, 115V).

LED Current Setting pin; configures the baseline operating current for the backlight arrays.

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

By respecting the datasheet’s limits and applying the principles above, you will harness the full potential of the SN51DP in your next embedded or industrial project.

: Connect a 10kΩ resistor directly from Pin 9 (COMP) to GND (Pin 4) . This changes the loop voltage profile and stops the IC from entering a hardware shutdown state. Direct Cross-References and Drop-In Equivalents This symptom usually signals that the via its

Used extensively as the driver cornerstone in budget-to-midrange 32-inch to 55-inch LED TVs .

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.

Housed in a 10-pin SSOP10/MSOP10 package (approx. 3.9mm x 7.9mm), it is an ideal choice for space-constrained circuit designs. Application & Reliability
