NCP305LSQ20T1G Integrated Circuits (ICs)

The NCP305LSQ20T1G is a single chip power management device. It combines low-side FETs with a precise, adjustable and self-regulated power supervisor. This device provides precise current monitoring and protection, voltage and temperature monitoring and protection, and signaling of UV/OV levels with an accuracy rate of up to 3%.

The NCP305LSQ20T1G is a relatively simple power management device, yet it achieves such a high level of accuracy. It works by monitoring and regulating by measuring the electrical current and voltage of an input, comparing it to a predetermined threshold, then acting accordingly. It does this by extracting a reference voltage from the input that is proportional to the current flowing and comparing it with a configured threshold. If the measured current exceeds the threshold, the device shuts down to protect the power line from damage. In addition, the device can be configured with internal or external temperature sensing to provide over-temperature protection. The device is also designed to respect wide supply voltage ranges from 3.3 V to 22 V.

The versatile NCP305LSQ20T1G is most suitable for application in server, data storage and computing systems, AC-DC and DC-DC converters, and other power management systems. It is especially useful when voltage and current flexibility is required. For example, if an application needs to regulate voltage over a wide range of values, the NCP305LSQ20T1G can be configured to monitor, measure and adjust the input to provide the most precise levels of accuracy. Furthermore, the low-side FET capability makes it a powerful solution for applications that require even lower levels of current accuracy.

In short, the NCP305LSQ20T1G is an advanced power management device with precise current monitoring and protection, voltage and temperature monitoring and protection, and signaling of UV/OV levels with an accuracy rate up to 3%. It is most suitable for AC-DC and DC-DC converter applications, server and data storage systems, and other power management systems.
