The TSC1801 is designed for motor control, solar power, and automotive power conditioning applications. Its fast response enables pulse-by-pulse current control, even in high-frequency power management systems. Additionally, it provides rapid over-current detection, protecting sensitive output-stage components from potential damage in case of faults.

Technical Specifications and Features

• Architecture: The TSC1801 is a single-operational-amplifier differential amplifier with built-in gain-setting resistors.

• Gain and Accuracy:

• Provides a fixed gain of 20V/V.

• Ensures an accuracy of 0.15% across the full temperature range.

• Maintains a total output error of less than 0.5%.

• Offers a maximum offset voltage of ±200μV.

• Future Versions: Additional models with 5V/V and 50V/V gain will be released.

• 

Electrical Performance

• Bidirectional Measurement Capability: The device supports bidirectional current sensing, subject to Vref limitations.

• Input and Reference Voltage Limits:

• Inputs and reference voltage must not drop more than 400mV below the negative supply rail or exceed the positive supply rail by more than 300mV.

• Inputs can slightly exceed these limits if the current remains below 10mA.

• Operating Conditions:

• Operates within a voltage range of 2V to 5.5V.

• Supports an extended temperature range from -40°C to +125°C.

Automotive Applications and Certifications

• Automotive-grade versions are available, qualified and characterized according to AEC-Q100 and Q003 standards.

• Undergoes advanced screening in compliance with AEC-Q001 and Q002.

• Automotive versions are scheduled for release in the second quarter of this year.

Conclusion

With its high precision and fast response, the TSC1801 is an ideal solution for high-frequency power management applications. Its robust performance and automotive-grade reliability make it suitable for a wide range of industrial and automotive applications.
