Current Sense Amplifiers

onsemi Current Sense Amplifiers monitor current consumption, providing critical information that can assist in the safety and diagnostic functions in a system. These Current Sense Amplifiers minimize BOM space and allow for system flexibility. They are low-cost, highly accurate, power-efficient, and offer minimal impact to battery life. onsemi offers cost-effective standalone Op-Amps and Current Sense Amplifiers that integrate external resistors to offer higher accuracy, smaller solution.
