LTC6101HVCCS5 High Voltage, High Side Current Sense Amplifier

The LTC6101HVCCS5 is a high-performance current sense amplifier from Linear Technology, designed to monitor current via the voltage across a shunt resistor in high voltage systems. This precision amplifier is ideal for a wide range of applications, including but not limited to automotive, industrial, power management, and battery monitoring systems.

With an operating voltage range from 4V to 100V, this device is capable of functioning in environments with high common mode voltages, ensuring reliability and accuracy even under stressful conditions. The LTC6101HVCCS5 offers a bidirectional current sensing capability, making it versatile for both charging and discharging applications in battery-powered systems.

The device features a quiescent current of just 170µA, which is significantly lower than many other high voltage amplifiers, leading to better power efficiency. This is particularly important for battery-operated devices where power conservation is critical. The LTC6101HVCCS5 also has a maximum offset voltage of 250µV, allowing for precise current measurement without significant error introduced by the amplifier itself.

Another key feature of the LTC6101HVCCS5 is its ability to withstand voltages up to 135V, providing a buffer for transients and overvoltage conditions. This robustness makes it suitable for applications where voltage spikes are common, ensuring that the device remains operational and protected against unexpected voltage increases.

The LTC6101HVCCS5 is available in a compact, 5-lead SOT-23 package, making it ideal for space-constrained applications. Its small footprint does not compromise its performance or reliability, which are hallmarks of Linear Technology's product offerings.

Overall, the LTC6101HVCCS5 is a highly reliable and accurate solution for current sensing in high voltage applications. Its robust design, low power consumption, and precision make it an excellent choice for designers looking to enhance the safety and efficiency of their electrical systems.
