XTR305IRGWR – TEXAS INSTRUMENTS

The XTR305IRGWR is a high-side current-sense amplifier optimized for automotive applications requiring precise current monitoring in harsh environments. This monolithic integrated circuit utilizes a high-bandwidth, low-offset operational amplifier architecture to accurately measure currents up to 50A with a voltage drop of less than 100mV at full scale. It operates from a single 5V to 24V supply, making it highly versatile. The device features an integrated current-limiting circuit for overcurrent protection and incorporates thermal shutdown to prevent damage from excessive temperature rise. The output signal is a linear voltage proportional to the sensed current, typically requiring minimal external components for signal conditioning. Packaged in a space-saving SOIC-8 surface-mount format, the XTR305IRGWR exhibits excellent common-mode rejection and noise immunity, crucial for accurate current measurement in noisy automotive electrical systems. Its key advantages include low power consumption, high accuracy, and robust protection features, making it ideal for battery management systems (BMS), motor control units (MCUs), and load monitoring circuits within vehicles. The device’s wide operating voltage range and compact size contribute to simplified design and improved system reliability.
