Diodes Incorporated ZXCT199Q Bidirectional Current Monitors
Diodes Incorporated ZXCT199Q Bidirectional Current Monitors are automotive AEC-Q qualified and developed to handle very low sense voltages, allowing the use of very low-value sense resistors to monitor large currents. The low offset voltage and zero-drift architecture enable current sensing with maximum drops spanning the shunt to as low as 10mV full-scale. The ZXCT199Q series has three fixed voltage gain options: 50V/V, 100V/V, and 200V/V. The device measures the voltage over shunts at common-mode voltages from -0.1V to 26V, separate from the supply voltage.
The Diodes Incorporated ZXCT199Q Monitors OUT pin has a voltage proportional to the load current, which can then be processed with an ADC. These devices are created with zero-drift architecture and manufactured utilizing post-trim technology to accomplish low offset voltage, low gain drift, and low gain error over the entire temperature range for precise measurement.
The ZXCT199Q performs from a 2.7V to 26V power supply with a maximum supply current of 100μA. All versions are available in the SOT363 package and have a temperature range of -40°C to +125°C.
