ZXCT199Q  
26V, ZERO-DRIFT, BIDIRECTIONAL, HIGH PRECISION CURRENT MONITOR  
Description  
Pin Assignments  
The DIODES ZXCT199Q series are automotive AEC-Q qualified  
current shunt monitors which 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 ZXCT199Q series have three fixed voltage gain options in 50V/V,  
100V/V, and 200V/V. They can measure voltage across shunts at  
common-mode voltages from -0.1V to 26V, independent of supply  
voltage.

SOT363  
OUT pin is a voltage proportional to the load current. It can then be  
processed with an ADC. These devices are designed with zero-drift  
architecture and manufactured by post trim technology to achieve low  
offset voltage, low gain drift and low gain error over full temperature  
range for precise measurement.  
Applications  
The ZXCT199Q is well suited for power supplies running at large current  
flow requiring the use of low-value sense resistors.  
These devices 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.

The ZXCT199Q has been qualified to AEC-Q100 Grade 1 and is  
automotive grade supporting PPAPs.
