Introducing the INA381A3IDSGR from Texas Instruments

The INA381A3IDSGR is a state-of-the-art voltage output current shunt and digital comparator integrated into a single package, designed and manufactured by the reputable Texas Instruments. This device is a part of the INA381 family, which is known for its precision and reliability in various applications ranging from power management to system monitoring.

At the core of the INA381A3IDSGR is a high-precision current-sensing amplifier that enables accurate measurement of the voltage across a shunt resistor. This feature allows for precise current monitoring of loads, which is essential in applications that demand tight current control such as battery chargers, power supplies, and energy management systems.

One of the standout features of this product is its integrated comparator with a latched/transparent output and a reference pin. This functionality allows for setting a precise threshold level for the current, which when exceeded, can trigger an alert to the system. This is particularly useful for overcurrent protection, ensuring that your system remains safe and operates within its designed parameters.

The INA381A3IDSGR offers a wide input common-mode voltage range from -0.2V to +26V, making it versatile for both low-side and high-side current sensing applications. Additionally, the device boasts a quiescent current of only 350 µA, which is beneficial for power-sensitive applications.

Designed for ease of use, the INA381A3IDSGR comes in a compact 10-pin WSON package, which is suitable for space-constrained applications. The device is also fully specified over the extended operating temperature range of -40°C to +125°C, ensuring reliable performance across a broad range of environmental conditions.

Whether you are developing power management systems, motor controls, or simply need precise current monitoring, the INA381A3IDSGR from Texas Instruments is an excellent choice that combines accuracy, reliability, and functionality in a small form factor. With its advanced features and robust design, it stands out as a superior solution for your current sensing and system protection needs.
