INA302A1IPW

Current Regulation/Management Overview

The INA302A1IPW is a current sense amplifier manufactured by Texas Instruments, housed in a 14-TSSOP package. It supports bidirectional current sensing with an input voltage range of 0V to 36V. The device features a fixed gain of 20 V/V and operates within a temperature range of -40°C to +125°C. Key electrical specifications include a maximum supply voltage of 5.5V, a minimum of 2.7V, and a typical operating supply current of 850µA. It offers a gain error of 0.02%, a common-mode rejection ratio (CMRR) of 120 dB, and an input offset voltage of 15µV.

Current Regulation/Management Feature Summary

• Supports high-side and low-side current sensing applications
• Provides bidirectional measurement capability for accurate monitoring
• Features high precision with low input offset voltage and bias current

Current Regulation/Management Applications

• Current monitoring in power distribution systems
• Battery management systems
• Overcurrent protection circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix IPW to confirm the TSSOP-14 package type and tape-and-reel or tube availability depending on distributor stock. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the design accommodates the specified operating temperature range and supply voltage constraints for reliable operation.

Current Regulation/Management Selection Notes

Select this component when a fixed 20 V/V gain is required for precise current monitoring. It is suitable for designs needing bidirectional sensing within a 36V common-mode range. Consider the INA302A2 variant if a different gain factor is necessary, or the INA303 series for higher bandwidth requirements.

Current Regulation/Management Part Context

This part belongs to the INA302 family of current sense amplifiers from Texas Instruments. The family is designed for high-precision current monitoring in industrial and consumer electronics. The A1 suffix typically denotes a specific gain setting within the product line, distinguishing it from other gain variants like A2.

Current Regulation/Management Replacement Considerations

The INA302A2IPW serves as a functional alternative within the same package, offering a different fixed gain. For automotive applications, the INA302A2QPWRQ1 provides equivalent functionality with AEC-Q100 qualification.
