INA302A1IPWR

Current Regulation/Management Overview

The INA302A1IPWR is a high-speed current sense amplifier manufactured by Texas Instruments, housed in a 14-TSSOP surface-mount package. It features a fixed gain of 20 V/V and supports bidirectional current sensing with an input common-mode voltage range extending from 0V to 36V. The device operates on a single supply voltage between 2.7V and 5.5V, drawing a typical operating supply current of 850µA. Key electrical specifications include a gain error of 0.02%, an input offset voltage of 15µV, and a gain-bandwidth product of 550kHz. It provides a common-mode rejection ratio of 120dB and maintains functionality across an extended industrial temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Supports bidirectional current sensing for both high-side and low-side applications within a wide common-mode voltage range.
• Delivers high precision with a fixed gain of 20 V/V, minimal gain error, and low input offset voltage.
• Provides high common-mode rejection ratio to ensure accurate signal processing in noisy environments.

Current Regulation/Management Applications

• High-side and low-side current monitoring in power distribution systems
• Battery management systems requiring precise charge and discharge tracking
• Overcurrent protection circuits in industrial equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix IPWR corresponds to the 14-TSSOP package and tape-and-reel shipping configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the fixed gain of 20 V/V aligns with your system's signal conditioning needs before procurement.

Current Regulation/Management Selection Notes

Select this component when a fixed gain of 20 V/V is required for bidirectional current sensing up to 36V common-mode voltage. It is suitable for designs needing high accuracy with low offset voltage and high CMRR. Consider the 850µA supply current and 14-TSSOP footprint for space-constrained PCB layouts.

Current Regulation/Management Part Context

This part belongs to the INA302 family of current sense amplifiers from Texas Instruments. It shares architectural similarities with the INA303 but differs in specific performance parameters such as gain bandwidth and offset characteristics. The INA302 series is designed for general-purpose high-precision current monitoring applications.

Current Regulation/Management Replacement Considerations

The INA302A2IPWR serves as a functional alternative within the same family, offering a different fixed gain configuration. Verify that the gain difference does not impact system calibration or signal scaling requirements before substitution.
