INA208AIPW

Current Regulation/Management Overview

The INA208AIPW is a unidirectional current-shunt monitor manufactured by Texas Instruments, housed in a 14-pin TSSOP package. It features a fixed voltage gain of 100 V/V and supports an input common-mode voltage range from -16 V to 80 V. The device operates with a supply voltage between 2.7 V and 18 V, drawing a typical operating supply current of 2.8 mA. It includes dual comparators and a voltage reference output. The component is rated for operation within a temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Unidirectional high-side current monitoring with integrated dual comparators
• Fixed high gain of 100 V/V for precise shunt voltage amplification
• Wide common-mode input voltage range supporting -16 V to 80 V
• Integrated voltage reference output for external circuit biasing

Current Regulation/Management Applications

• High-side current sensing in industrial control systems
• Battery management and protection circuits
• Power supply overcurrent detection
• Motor drive current monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'IPW' corresponds to the TSSOP-14 package and A-grade accuracy. Confirm RoHS compliance status via the latest manufacturer datasheet. Check for product change notifications regarding pinout or electrical characteristics before finalizing procurement. Ensure the source document explicitly lists INA208AIPW as the active part number.

Current Regulation/Management Selection Notes

Select this component when a fixed 100 V/V gain is required for unidirectional current measurement. It is suitable for applications requiring wide common-mode voltage tolerance up to 80 V. The integrated comparators simplify overcurrent protection logic without external components. Consider the INA206 or INA207 if different gain factors such as 20 V/V or 50 V/V are needed instead.

Current Regulation/Management Part Context

The INA208AIPW belongs to the INA20x family of current-shunt monitors from Texas Instruments. This series provides high-precision amplification for shunt resistors. The INA208 variant specifically offers a 100 V/V gain, distinguishing it from the lower-gain INA206 (20 V/V) and INA207 (50 V/V). All variants share similar pinouts and comparator functionalities.

Current Regulation/Management Replacement Considerations

Public confirmed substitute part numbers include INA208AIPWR. Verify that the replacement maintains the same TSSOP-14 package and 100 V/V gain specification.
