INA205AIPW

Current Regulation/Management Overview

The INA205AIPW is a unidirectional current shunt monitor manufactured by Texas Instruments, designed for high-side measurement applications. It operates within a supply voltage range of 2.7 V to 18 V and supports common-mode input voltages from -16 V to 80 V. The device features a typical quiescent current of 2.8 mA and is housed in a 14-TSSOP package suitable for surface-mount installation. It functions reliably across an operating temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Supports high-side current sensing with wide common-mode voltage tolerance
• Provides accurate monitoring of current flow through external shunt resistors
• Operates with low power consumption suitable for battery-powered systems

Current Regulation/Management Applications

• Industrial process control systems requiring precise current feedback
• Power distribution units for monitoring load currents
• Overcurrent protection circuits in electronic equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-14 package variant rather than other packaging options like DR or DGK. Confirm that the A-grade accuracy specification meets the design requirements for precision monitoring tasks. Ensure compatibility with the intended common-mode voltage levels up to 80V during system integration.

Current Regulation/Management Selection Notes

Select this component when unidirectional high-side measurement is required with a maximum common-mode voltage of 80V. It is appropriate for designs needing a 14-pin surface-mount solution with moderate bandwidth. Consider alternative models if bidirectional sensing or higher precision grades are necessary for the specific application constraints.

Current Regulation/Management Part Context
