Enhancing System Protection with Current Sense Amplifiers

In servers, storage systems, networking equipment and notebooks, response speed and measurement accuracy directly determine the reliability of current monitoring and protection. High precision, fast response current sense amplifiers are essential to ensure stable operation.

Compared with digital approaches, analog current sense amplifiers deliver faster response and lower signal latency, enabling real time current detection with continuous, high resolution data. Their simpler design and independence from ADC constraints make them well suited to real time control and overcurrent protection.

Richtek's latest analog current sense amplifiers, the RTQ6060A/RTQ6060B, provide accurate and real time current monitoring:

	-0.3V to 36V common mode range, supporting high/low side and bidirectional sensing, offering design flexibility
	High accuracy with maximum gain error of ±0.4% across the full temperature range (RTQ6060A), improving reliability
	6 gain options from 50V/V to 1000V/V for flexible design
	Max 100µA quiescent current at room temperature, balancing performance and efficiency
