INA303A3IPW

Current Regulation/Management Overview

The INA303A3IPW is a high-precision, bi-directional current sense amplifier from Texas Instruments. It features a fixed gain of 50 V/V and operates with a supply voltage range of 2.7 V to 5.5 V. The device supports a common-mode voltage up to 36 V and includes dual integrated window comparators for overcurrent protection. Key electrical specifications include a gain error of 0.05%, a bandwidth of 450 kHz, and a slew rate of 4 V/µs. It functions within an operating temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Bi-directional current sensing capability supporting both high-side and low-side configurations
• Dual integrated window comparators providing alert functionality for overcurrent protection
• High precision performance with low input offset voltage and drift characteristics

Current Regulation/Management Applications

• Overcurrent protection in industrial systems
• Current monitoring in battery management systems
• Power supply regulation and management circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix IPW corresponds to the TSSOP-14 package variant. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the fixed 50 V/V gain meets your signal conditioning needs without external resistor adjustments.

Current Regulation/Management Selection Notes

Select this component when a fixed 50 V/V gain is required for precise current measurement. The integrated comparators simplify design by eliminating external threshold detection components. Consider the 36 V common-mode range for applications involving higher voltage buses or floating loads.

Current Regulation/Management Part Context

This part belongs to the INA303 family of 36-V current sense amplifiers. It shares architectural similarities with the INA303A1 and INA303A2 but differs in its fixed internal gain setting. The A3 designation specifically indicates the 50 V/V gain configuration, distinguishing it from other variants in the series.

Current Regulation/Management Replacement Considerations

INA303A3IPWR serves as the reel-pack equivalent for surface-mount assembly variations.
