The ON Semiconductor NCS199A3RSQT2G is a precision current sense amplifier that offers a high level of performance for power management applications. This device is designed to provide accurate current measurement for system monitoring and control, making it ideal for a wide range of applications, including power supply control, battery management, and overcurrent protection.

Featuring a wide common-mode voltage range of 2V to 26V, the NCS199A3RSQT2G is versatile and can be used in systems with varying power levels. It has a voltage output that makes it easy to interface with analog-to-digital converters (ADCs) or directly with microcontrollers for further processing. The device's precision is enhanced by a low input offset voltage, which ensures that the current measurement is accurate and reliable.

With a gain of 20 V/V, the NCS199A3RSQT2G amplifies the voltage across a shunt resistor placed in the path of the current to be measured. This allows for the detection of very small voltage drops and, hence, the measurement of current with high accuracy. Additionally, the quiescent current is low, contributing to the overall energy efficiency of the system in which it is used.

The NCS199A3RSQT2G is available in a compact, lead-free TSOP-6 package, which is suitable for space-constrained applications. It also supports a wide operating temperature range of -40°C to +125°C, providing reliable performance across various environmental conditions.

ON Semiconductor has designed the NCS199A3RSQT2G with industry-standard ESD protection, ensuring robustness and longevity in the field. The device is RoHS compliant, reflecting ON Semiconductor's commitment to environmental sustainability. With its combination of precision, versatility, and durability, the NCS199A3RSQT2G is an excellent choice for designers looking to implement accurate current sensing in their electronic systems.
