INA204AIPW

Current Regulation/Management Overview

The INA204AIPW is a high-speed, unidirectional current shunt monitor manufactured by Texas Instruments. It features an input voltage range of -16 V to 80 V and operates on a single supply from 2.7 V to 18 V. The device provides a voltage output proportional to the sensed current with a typical accuracy of ±3.5%. It integrates dual comparators and a precision reference within a 14-pin TSSOP package.

Current Regulation/Management Feature Summary

• Supports both low-side and high-side current sensing configurations
• Integrates dual comparators for overcurrent protection applications
• Includes an internal precision reference voltage source

Current Regulation/Management Applications

• High-side or low-side current monitoring in power systems
• Overcurrent protection circuits requiring fast response times
• Battery management systems and industrial power supplies

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-14 package variant when sourcing. Confirm that the required operating temperature range aligns with the specified limits. Ensure the application circuit respects the maximum input common-mode voltage constraints. Check for any recent product change notifications regarding pinout or electrical characteristics updates before finalizing the design.

Current Regulation/Management Selection Notes

Select this component when bidirectional sensing is not required but high-speed response is critical. Consider the integrated comparator functionality if external logic is needed for fault detection. Evaluate the trade-off between the fixed gain accuracy and the wide input voltage range. Ensure the PCB layout supports the thermal requirements of the TSSOP-14 package under continuous load conditions.

Current Regulation/Management Part Context

This part belongs to the INA20x family of current shunt monitors designed for robust performance in harsh environments. It complements other variants like the INA202 and INA205 by offering higher speed and additional comparator features. The family targets applications needing reliable current measurement without complex external signal conditioning.
