SN6505 Description

Short technical summary and product information.

The SN6505 from Texas Instruments is a push-pull transformer driver engineered for creating small, isolated power supplies with ultra-low noise and EMI. It supports a wide input voltage range of 2.25 V to 5.5 V and provides a high output drive of 1 A at a 5 V supply. Key features include low on-resistance (0.25 Ω max at 4.5 V), slew-rate control, and spread spectrum clocking to minimize electromagnetic interference.

 

This device is suitable for various applications requiring isolated power, such as CAN, RS-485, RS-422, RS-232, SPI, I2C, and low-power LAN interfaces, as well as low-noise isolated USB supplies. It includes integrated protection features like 1.7 A current limiting, thermal shutdown, and under-voltage lockout. The SN6505 is available in a compact 6-pin SOT23 package, making it ideal for space-constrained designs. The operating temperature range is from –55°C to 125°C.
