SN6505DQDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments SN6505DQDBVRQ1 is an automotive-qualified, low-noise transformer driver suitable for isolated power supply applications. It features a wide input voltage range from 2.25 V to 5.5 V and provides a high output drive of 1 A at a 5 V supply.

 

Key electrical characteristics include a maximum output voltage of 16 V and a switch current limit of 2 A. The device operates with a switching frequency between 363 kHz and 517 kHz. It also boasts a low on-resistance of 0.25 Ω maximum at a 4.5 V supply and a low shutdown current of less than 1 µA.

 

Designed for reliability, the SN6505DQDBVRQ1 includes features such as short-circuit protection, slew-rate control, spread spectrum clocking, and thermal shutdown. It is AEC-Q100 (Grade 1) qualified for automotive applications and operates within a temperature range of -40°C to 125°C.

 

The component is housed in a compact 6-pin SOT-23 (DBV) package, making it suitable for space-constrained designs. Its push-pull driver architecture is optimized for transformer-based isolated power supplies.
