INA381A1IDSGT - Texas Instruments

The INA381A1IDSGT is a sophisticated, high-precision current-sense amplifier with an integrated comparator from Texas Instruments, designed for a wide range of applications requiring accurate current monitoring. This device is part of TI's industry-leading portfolio of current-sense amplifiers that offer a variety of features to meet different system requirements.

Featuring a bidirectional, high-side current-sense amplifier, the INA381A1IDSGT provides a voltage output that is proportional to the current passing through a shunt resistor. This allows for precise current measurement in both charging and discharging states of a battery, for instance. The integrated comparator with a latched output enables the INA381A1IDSGT to offer over-current protection by comparing the sensed voltage to a user-set threshold, triggering an alert for system protection.

This device is highly accurate, with a maximum offset voltage of 35 µV and a gain error of only 0.5%, ensuring reliable performance in critical applications. The INA381A1IDSGT operates over a wide common-mode voltage range from 2.7V to 5.5V, which makes it suitable for a variety of supply rails. Additionally, the wide input common-mode range of 0V to 26V is compatible with systems that have significant voltage swings, such as automotive and industrial applications.

The INA381A1IDSGT is available in a compact, 10-pin WSON package, making it ideal for space-constrained applications. Moreover, it has a specified temperature range from -40°C to 125°C, ensuring reliable operation in extreme environments. With its precision, integration, and robustness, the INA381A1IDSGT from Texas Instruments is an excellent choice for power management, overcurrent protection, and battery monitoring in applications such as power supplies, motor controls, and consumer electronics.
