Richtek's RTQ6052 is a high-side current-shunt monitor specifically designed for industrial applications. It integrates a current-sense amplifier, bandgap reference, and a comparator with a latching output. The RTQ6052 excels at sensing drops across shunts at common-mode voltages ranging from 2 V to 80 V, offering precise current measurement capabilities.
One of the key features of the RTQ6052 is its support for a 100 V/V output voltage scale. This allows for accurate representation and scaling of the sensed current, providing valuable information for system monitoring and control.
The RTQ6052 includes a built-in open-drain comparator and an internal reference that provides a 0.6 V threshold. By using external dividers, users can set the desired current trip point, enabling customizable current threshold detection. Additionally, the comparator features latching capability, which can be easily achieved by grounding or leaving open the RESET pin. This latching functionality ensures that the detected events are captured and held, enhancing the reliability of the monitoring system.
The RTQ6052 is available in a compact 8-pin MSOP package, allowing for space-efficient designs and easy integration into various industrial applications.
In summary, Richtek's RTQ6052 high-side current-shunt monitor offers a reliable and precise solution for industrial current sensing applications. With its wide range of common-mode voltages supported, 100 V/V output voltage scale, and latching capability, it provides accurate and customizable current monitoring capabilities in a compact form factor.
