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.
• 50mA to 20A Current Sense
• Low-side or High-side Current Sensing
• Single-Supply
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
