The SC8450/60 series is a high-precision current sensor chip with fault protection function that can measure 150A. Its wide-body SOP-16 package achieves current wire impedances as low as 0.25mΩ, making it suitable for use in power systems requiring measurements up to 150A. It is the best solution for automotive OBC, EPS, charging pile, DC-DC converter applications.

The SC8450 series adds fast and slow fault monitoring for open-drain outputs, and its built-in FLAG_F uses a built-in fixed fault threshold, which does not require any additional components and achieves 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.
