TIINA300AQDGSRQ1
Overview
The INA300AQDGSRQ1 is an automotive-qualified, high-side or low-side current-sense comparator designed for overcurrent protection in demanding environments. It monitors the voltage drop across a shunt resistor and compares it against a programmable threshold, offering a wide common-mode range from 0V to 36V. The device features an open-drain output with selectable latching modes and response times as fast as 10 microseconds.
Why Choose This Part
This AEC-Q100 qualified comparator integrates a precise current-sensing front end with a programmable threshold, significantly reducing component count compared to discrete op-amp and comparator designs. It supports selectable response times to filter out transient current spikes and offers a low quiescent current of 135 microamps (maximum) to minimize power drain.
Applications
Key Specifications
Getting Started
To evaluate this part, use the INA300EVM evaluation module which allows for easy configuration of the threshold and response time via external resistors. Engineers should calculate the shunt resistor value based on the target current limit and ensure the VDD supply stays within the 2.7V to 5.5V range.
