INA303-Q1

Overview

The INA302-Q1 and INA303-Q1 (INA30x-Q1) devices feature a high common-mode, bidirectional, currentsensing amplifier and two high-speed comparators to detect out-of-range current conditions. The INA302Q1 comparators are configured to detect and respond to overcurrent conditions.
