TIDA-00328 Reference Design

Texas Instruments

50 mA-20 A: Single-Supply: Low-Side or High-Side Current Sensing Solution

Description

This TI Reference Design implements a low-side or high-side wide dynamic range current sensing solution.  Wide dynamic range is achieved by a unique gain switching method.  Switching gain in hardware allows a faster response time than what can typically be achieved with other methods.  The implementation utilizes the INA225: high-speed: multiple gain current shunt monitor along with the INA300 current shunt monitor comparator with open drain output.

Features
  • • 50mA to 20A Current Sense• Low-side or High-side Current Sensing• Single-Supply
