Overview
The VN5770AKP-E is a quad smart power solid state relay produced by STMicroelectronics. This device is composed of three monolithic chips housed in a standard SO-28 package, featuring a double high-side switch and two low-side switches. The high-side switches are built using STMicroelectronics' VIPower M0-5 technology, while the low-side switches utilize VIPower M0-3 OMNIFET II technology. This configuration makes the VN5770AKP-E suitable for driving DC motors in bridge configurations as well as serving as a quad switch for various low voltage applications.
