The circuit in Figure 1 shows a typical example of high-side current sense. Negative feedback tries to force the voltage V SENSE upon gain resistor R GAIN. The current through R GAIN flows through ...
Negative voltage sources are widely used in various applications such as computing systems, liquid-crystal display (LCD) source drivers and audio amplifiers Zach Zhang, Staff Applications Engineer, ...
A high-side current-sense amplifier must be protected against reversed battery connections or inductive kickbacks or other negative-voltage transient. This Idea for Design describes a circuit using ...
