INA302A2IPWR

Current Regulation/Management Overview

The INA302A2IPWR is a dual-channel current sense amplifier manufactured by Texas Instruments, housed in a 14-TSSOP surface-mount 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 on a single supply voltage between 2.7V and 5.5V. Key electrical specifications include a maximum input offset voltage of 15µV, a gain error of 0.02%, and a quiescent current of 850µA per channel. It functions within a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Provides high-accuracy bidirectional current monitoring for both high-side and low-side configurations.
• Integrates precision internal gain to minimize external component requirements.
• Supports wide common-mode voltage operation up to 36V.

Current Regulation/Management Applications

• Battery management systems
• Industrial process control
• Power supply current limiting

Current Regulation/Management Procurement Notes

Verify the specific suffix IPWR indicates the tape-and-reel packaging format compatible with automated assembly lines. Confirm that the A2 variant corresponds to the required gain setting and accuracy class for your design. Ensure the 14-TSSOP footprint matches your PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to your manufacturing region.

Current Regulation/Management Selection Notes

Select this component when precise differential voltage amplification is required across a wide common-mode range. The dual-channel architecture allows simultaneous monitoring of two distinct current paths within a single package. Consider the 20 V/V gain factor to ensure the output signal remains within the ADC input range of your microcontroller or data acquisition system.

Current Regulation/Management Part Context

This part belongs to the INA302 family of current sense amplifiers designed for robust performance in demanding environments. The IPWR suffix denotes the specific reel-based packaging used for high-volume production. It serves as a specialized solution for applications requiring accurate current feedback without the need for external shunt resistors or complex calibration circuits.

Current Regulation/Management Replacement Considerations

Consult official documentation for direct pin-compatible alternatives within the same product family. Verify that any substitute maintains the 36V common-mode voltage limit and 20 V/V gain specification. Ensure thermal performance and package dimensions are identical to avoid mechanical integration issues.
