INA300AIDSQR Description

Short technical summary and product information.

The Texas Instruments INA300AIDSQR is an analog output current sense comparator with an integrated comparator, designed for overcurrent protection applications. It operates over a wide common-mode voltage range from 0 V to 36 V, allowing it to measure differential voltage signals on common-mode voltages that can vary significantly.

 

Key electrical specifications include a maximum input offset voltage of ±500 µV and a maximum offset voltage drift of 0.5 µV/°C. The device offers selectable response times of 10 µs, 50 µs, or 100 µs, and a programmable threshold voltage adjustable from 0 mV to 250 mV using a single resistor. It also features selectable hysteresis options of 2 mV, 4 mV, or 8 mV.

 

This comparator has an active quiescent current of 135 µA maximum and a disabled quiescent current of 3.5 µA maximum. It provides an open-drain output with an available latch mode. The INA300AIDSQR is available in a 10-WSON (2x2 mm) package and a 10-WFDFN exposed pad package, both suitable for surface mounting.

 

With its robust features and wide operating range, the INA300AIDSQR is well-suited for applications requiring precise current monitoring and overcurrent detection.
