The DIODES™ ZXCT199 series of current shunt monitors are designed to deal with very low sense voltages, enabling the use of very low value sense resistors to monitor large currents. The low offset voltage and zero-drift architecture enables current sensing with maximum drops across the shunt to as low as 10mV full-scale.
The ZXCT199 series has three fixed voltage gain options in 50V/V, 100V/V, and 200V/V. It can measure voltage across shunts at common-mode voltages from -0.1V to 26V, independent of supply voltage.
These parts operate from a 2.7V to 26V power supply with a maximum supply current of 100μA. All versions have a temperature range of -40°C to 125°C, and are offered in the SOT363 package.

For automotive applications requiring specific change control(i.e. parts qualified to AEC-Q100/101/104/200, PPAP capable, and manufactured in IATF16949 certified facilities), please contact us or your local Diodes representative.
Diodes Incorporated's current monitors are high-performance, high-side/power rail current measurement ICs. They greatly simplify the measurement of load currents without disturbing the ground plane/reference point.
The current monitor families contain variants with quiescent currents as low as 3µA, and others with operating voltages up to 60V, proving solutions for overcurrent detection in consumer, industrial, and automotive applications. The portfolio includes current output variants which via an external resistor to ground to provide adjustable gain, and voltage output variants with fixed gains.
Automotive-compliant variants are available which are qualified to AEC-Q100 Grade 1 in IATF 16949 facilities supporting PPAP documentation.
