SN6505AQDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments SN6505AQDBVRQ1 is a low-noise, 1-A transformer driver with soft start, suitable for automotive applications. It features a wide input voltage range from 2.25 V to 5.5 V and a high output drive capability.

 

Key electrical specifications include a typical output current of 1 A and a maximum output current of 1.5 A. The device operates with a switching frequency ranging from 138 kHz to 203 kHz, with a specific internal oscillator option of 160 kHz for the SN6505A-Q1 variant. It also includes features like short-circuit protection, slew-rate control, spread spectrum clocking, and thermal shutdown.

 

This transformer driver is housed in a compact 6-pin SOT-23 (DBV) package, designed for surface mount applications. The operating temperature range is -40°C to 125°C (TA), making it suitable for demanding environments. The device is AEC-Q100 (Grade 1) qualified for automotive applications and is Functional Safety-Capable.

 

Applications include isolated power supplies where low noise and reliable performance are critical. The soft-start feature helps reduce in-rush current during power-up.
