Sn51dp Datasheet «2024-2026»

The SN51DP is a power management IC primarily used as an LED backlight driver for liquid crystal display (LCD) televisions. Manufactured by On-Bright Electronics, it is commonly found in TV repair contexts, often replaced by or cross-referenced with the OB3350 CP driver IC. Key Technical Specifications Based on manufacturer data and technical listings features the following: Package Type: MSOP-10 (10-pin Surface Mount). Operating Voltage: Minimum 3.5V to Maximum 7V. Temperature Range: Operating from -20°C to 130°C.

• Absolute maximum ratings (clear).
• Electrical characteristics (graphical – IF vs trigger current, temperature effects).
• Zero-cross timing diagram (useful for timing-sensitive designs).
• Application notes (external triac, snubber design, PCB layout).
• Isolation and safety ratings (essential for regulatory approvals).

1. Understand the part number: Verify that you're looking at the correct datasheet for your specific part number.
2. Read the introduction and features section: Get an overview of the chip's capabilities and applications.
3. Focus on key specifications: Pay attention to electrical characteristics, switching characteristics, and application guidelines.

1. SN751DP (or SN75176DP) – Common RS-485 transceiver from Texas Instruments (often in PDIP-8 package).
2. SN51DP might be a misreading of SN54 or SN74 series (logic gates, flip-flops, etc.), e.g., SN74LS51N.
3. 5N51DP – Could be an optocoupler or hybrid IC (Sharp, Toshiba, etc.), but not standard.
