ZXCT1020E5TA

Overview

The ZXCT1020E5TA is a high-side current sense amplifier manufactured by Diodes Incorporated. It operates within an input voltage range of 2.5V to 20V and functions across a temperature range of -40°C to +85°C. The device provides a current output proportional to the sensed current, with a typical gain of 100V/V. It features low quiescent current consumption and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides accurate high-side current sensing for monitoring applications
• Operates with low supply current to minimize power loss
• Delivers a current output signal proportional to the load current

Applications

• Battery management systems
• Current limiting circuits
• Power supply monitoring

Procurement Notes

Verify the specific suffix E5TA corresponds to the standard reel packaging configuration when ordering. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits for your application environment. Ensure the input voltage does not exceed the maximum rating of 20V during operation.

Selection Notes

Select this component when high-side current monitoring is required in space-constrained designs. The SOT-23-5 package offers a small footprint suitable for portable electronics. Consider the 2.5V minimum supply voltage requirement to ensure compatibility with low-voltage systems.

Part Context

This part belongs to the ZXCT10xx series of current sense amplifiers from Diodes Incorporated. The series includes variants with different accuracies and gain settings. The ZXCT1020 specifically targets general-purpose current monitoring tasks requiring moderate precision and low power consumption.

Replacement Considerations

Direct substitutes include other parts from the ZXCT10xx family such as the ZXCT1021 or ZXCT1022, provided the accuracy and gain specifications meet the design requirements. Verify pinout compatibility before substitution.
