INA201AIDR

Current Regulation/Management Overview

The INA201AIDR is a high-side current shunt monitor manufactured by Texas Instruments, designed for precise current measurement in power management systems. It operates within a supply voltage range of 2.7 V to 18 V and supports input voltages from -16 V to 80 V. The device features an accuracy of 3.5% and consumes 1.85 mA of operating supply current. It is housed in an SOIC-8 surface-mount package and functions reliably across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports high-side current sensing with wide common-mode voltage tolerance
• Provides accurate current monitoring with specified gain error margins
• Operates on single low-voltage supplies suitable for portable applications

Current Regulation/Management Applications

• Battery protection circuits
• Overcurrent detection and protection
• Power supply current monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 3.5% accuracy specification meets the system's tolerance requirements for the intended current range. Ensure the input common-mode voltage does not exceed the 80 V limit during transient conditions.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a wide common-mode voltage range up to 80 V. Consider the INA201AIDR for applications needing a balance between accuracy and low power consumption. Evaluate the SOIC-8 package size against available PCB space constraints compared to other series members like the INA202 or INA283.

Current Regulation/Management Part Context

The INA201 belongs to the INA20x family of current shunt monitors from Texas Instruments. This series provides robust solutions for measuring current in various industrial and consumer electronics applications. The INA201 specifically targets high-side measurement scenarios where the shunt resistor is placed between the power source and the load.

Current Regulation/Management Replacement Considerations

The INA201AIDGKR serves as a pin-compatible alternative offering the same functionality in a VSSOP-8 package. Designers requiring a different footprint may consider this variant without modifying the circuit schematic.
