INA381A4QDGSRQ1 Description

Short technical summary and product information.

The Texas Instruments INA381A4QDGSRQ1 is an AEC-Q100 qualified current sense amplifier designed for automotive applications. It features a wide common-mode input range of -0.2 V to 26 V, allowing it to measure differential voltage signals on common-mode voltages independent of the supply voltage.

 

This device provides high accuracy with a gain error of 1% maximum at 25°C and an offset voltage drift of 1 µV/°C maximum. The integrated open-drain comparator includes hysteresis and supports transparent and latching modes for overcurrent detection. The total system overcurrent protection response time is less than 10 µs.

 

The INA381A4QDGSRQ1 is available in a 10-VSSOP package and operates over an ambient temperature range of -40°C to +125°C. Its functional safety-capable design and documentation aid in functional safety system design.

 

Key applications include ADAS domain controllers, body control modules, window modules, roof motor modules, seat position and fold modules, interior heater modules, telematics control units, digital cockpit processing units, and automotive head units.
