INA381A1IDGST

Current Regulation/Management Overview

The INA381A1IDGST is a precision current sense amplifier manufactured by Texas Instruments, housed in a 10-pin TSSOP package. It features a fixed gain of 2 V/V and supports a maximum common-mode voltage of 26 V. The device operates within a supply voltage range of 2.7 V to 5.5 V and maintains an operating temperature range from -40 °C to +125 °C. Key electrical specifications include a nominal common-mode rejection ratio (CMRR) of 100 dB, a maximum input offset voltage of 500 µV, and a bandwidth of 350 kHz.

Current Regulation/Management Feature Summary

• Integrated over-current comparator for fault detection
• Low-side capable operation with high common-mode voltage tolerance
• Zero-drift architecture for high DC accuracy

Current Regulation/Management Applications

• Battery management systems
• Industrial motor control
• Power supply monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix IDGST corresponds to the TSSOP-10 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure component authenticity by purchasing from authorized distribution channels to mitigate counterfeiting risks.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise low-side current measurement with integrated fault protection. The fixed 2 V/V gain suits scenarios where moderate signal amplification is sufficient. Evaluate thermal performance requirements against the specified 125 °C junction temperature limit during design.

Current Regulation/Management Part Context

This part belongs to the INA381 family of current sense amplifiers featuring integrated comparators. The 'A1' designation indicates a specific gain configuration within the series. The IDGST suffix identifies the plastic surface-mount TSSOP package type offered by Texas Instruments.

Current Regulation/Management Replacement Considerations

Consult official substitution guides for compatible alternatives such as the INA381A1IDSGT or INA381A1IDGSR. Verify pinout compatibility and parameter alignment before replacing the component in existing designs.
