High Side Driver

Enhancing the safety of automotive systems with high-precision current detection and protection functions by smart high-side drivers

Overview

Our smart high-side drivers not only enable the function of turning on and off the in-vehicle power supply, but also have the ability to identify abnormal conditions of the power supply, load, and environment, and feedback these conditions to the system, thereby enhancing the overall system safety level. They feature real-time high-precision current detection, current limiting protection, over-temperature protection, and are suitable for driving various types of resistive, inductive and capacitive loads.

Selection tool

Core advantages

Wide operating voltage range

Ultra low IQ
