Our integrated shunt digital power monitors simplify current sensing design by removing the need for an external shunt resistor. The integrated shunt enables low-temperature drift performance and calibration-equivalent measurement accuracy. TI’s EZShunt™ Technology offers both cost-optimized and high-accuracy complete current sensing solutions. The EZShunt™ Digital Power Monitor portfolio enables multi-modal sensing, freeing up MCU resources to be used for additional tasks.
