Frequently Asked Questions
What is the maximum common-mode voltage of the INA300AIDSQT?
The INA300AIDSQT supports a maximum common-mode voltage of 36V, allowing it to monitor currents on high-side rails up to 36V. This makes it suitable for a wide range of power management and industrial applications requiring high-voltage current sensing.
What are the typical applications for the INA300AIDSQT?
The INA300AIDSQT is commonly used in overcurrent protection, battery management systems, DC-DC converters, motor drives, and server power supplies. Its precise current-limit comparator function and open-drain output make it ideal for triggering protection responses when current exceeds a set threshold.
What package does the INA300AIDSQT come in?
The INA300AIDSQT is available in a 10-pin SON (Small Outline No-lead, S-PDSO-N10) package. This compact, leadless package minimizes PCB footprint and provides good thermal performance, making it well-suited for space-constrained designs.
What is the input offset voltage of the INA300AIDSQT?
The INA300AIDSQT has a maximum input offset voltage of 650µV at 25°C. This low offset voltage ensures accurate detection of overcurrent conditions, minimizing false triggers and improving the reliability of current protection circuits.
