SC844 series is a new member of Shanghai Xinggan Semiconductor's lightning all-integrated current sensor product line, and the industry's first fully integrated current detection chip that can pass the 20kA/8us lightning surge test.

The SC844 series adds fast and slow fault monitoring for open-drain outputs, and its built-in FLAG_F uses a built-in fixed fault threshold that does not require any additional components to achieve a fast protection response of<2uS, making it ideal for severe short-circuit fault detection. The FLAG_S supports users to set fault thresholds through peripheral voltage divider resistors, and has current pulse shielding settings to ignore interference in the application and prevent false alarms, which is very suitable for mild overcurrent detection and feedback peak setting. This feature is flexible in fault detection and greatly simplifies board application layout.
