Description
- TIDA-00328, 50mA - 20A Single-Supply, Low-Side or High-Side Current Sensing Solution Reference Design. This 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
