L9733XPTR ST Automotive Octal Low-Side Driver | PowerSSO-28 祼焊盘 | 8-Ch, 0.7A, 41V

Product Overview

The L9733XPTR is a monolithic octal low-side driver designed by STMicroelectronics for automotive and industrial applications. It integrates eight low-side drivers with a serial control interface, capable of driving resistive, inductive, and capacitive loads. Housed in a PowerSSO-28 package with exposed pad for enhanced thermal dissipation, it operates over a wide supply voltage range from 4.5V to 41V, with each output rated at 0.7A continuous current. The device features over-temperature and over-current protection, making it ideal for harsh environments.
