INA301A3IDGKT

Current Regulation/Management Overview

The INA301A3IDGKT is a high-precision current sense amplifier manufactured by Texas Instruments. It operates with an input voltage range of 0 V to 36 V and features a bandwidth of 550 kHz. The device offers a slew rate of 4 V/µs and includes an integrated comparator with an open-drain output. It is housed in an 8-pin VSSOP (DGK) package and is rated for operation across a temperature range of -40°C to 125°C.

Current Regulation/Management Feature Summary

• High-precision current sensing capability within a compact surface-mount package
• Integrated comparator function providing open-drain output for direct system interfacing
• Wide common-mode input voltage range supporting various power supply configurations

Current Regulation/Management Applications

• Overcurrent protection circuits
• Current monitoring in industrial systems
• Power management unit feedback loops

Current Regulation/Management Procurement Notes

Verify the specific suffix IDGKT corresponds to the 8-pin VSSOP package and -40 to 125°C temperature grade. Confirm moisture sensitivity handling requirements during storage and assembly. Ensure the ordering quantity aligns with manufacturer packaging standards, as this component may be subject to specific reel or cut-tape constraints defined by the distributor.

Current Regulation/Management Selection Notes

Select this component when a combined amplification and comparison function is required in a single package. The 550 kHz bandwidth suits applications requiring moderate speed response without the complexity of separate comparator stages. The 36 V common-mode range limits suitability for higher voltage bus architectures compared to 110 V variants.

Current Regulation/Management Part Context

This part belongs to the INA301 series of current sense amplifiers from Texas Instruments. It shares functional similarities with other devices in the family but is distinguished by its specific package type and integrated comparator feature. The series is designed for precision monitoring applications where space efficiency and signal integrity are critical design parameters.

Current Regulation/Management Replacement Considerations

The INA301A3IDGKR is a pin-compatible alternative in a different package format. Verify that the package change does not impact thermal performance or PCB layout constraints before substitution.
