WebUsing An Op Amp for High-Side Current Sensing Tim Claycomb, Marc Liu, Robert Clifton High-side current sensing is used in a wide range of applications such as battery chargers or overcurrent protection. Figure 1 displays a typical high-side current sensing schematic. The shunt resistor, Rshunt, is placed between the bus voltage and the system load. Webmode input voltage range (VCM) of the op amp must include ground. The MCP6H0X op amp is a good choice since its V CM is from VSS – 0.3V to V DD –2.3V. Considering the advantages, choose low-side current sensing where short circuit detection is not required, and ground disturbances can be tolerated. RSEN Op Amps Circuits ISEN ISEN VOUT …
