Current-Sense Amplifier with Dual Over Current Level Monitor & Alert Output
The project presented here is a high common-mode current sense amplifier with two high-speed comparators to detect out-of-range current conditions. The comparators are configured to detect and respond to dual over current conditions. These devices feature an adjustable limit threshold range for each comparator set using an external limit-setting resistor. Limit 1 Resistor is R10 and Limit 2 Resistor is R11. The board measures differential voltage signals on common-mode voltages that can vary from 0 V up to +36 V, independent of the supply.
