More Information

The INA302-Q1 and INA303-Q1 (INA30x-Q1) devices feature a high common-mode, bidirectional, current-sensing amplifier and two high-speed comparators to detect out-of-range current conditions. The INA302-Q1 comparators are configured to detect and respond to overcurrent conditions. The INA303-Q1 comparators are configured to respond to both overcurrent and undercurrent conditions in a windowed configuration. These devices feature an adjustable limit threshold range for each comparator set using an external limit-setting resistor. These current-shunt monitors can measure differential voltage signals on common-mode voltages that can vary from –0.1 V up to +36 V, independent of the supply. In addition, these devices will survive with common-mode voltages as high as 40 V.
