S-80913CNMC-G8HT2G

Power management integrated circuits (PMIC) play an important role in improving system performance, flexibility, and functionality. Supervisors, a specialized type of PMIC, are designed to monitor currents or voltages in the power supply rail and respond with a reset signal if any of those parameters exceed a predetermined limit. One example of a supervisor IC is the S-80913CNMC-G8HT2G, a popular supervisor IC offered by Silicon Labs. In this article, we will discuss the application field and working principles of the S-80913CNMC-G8HT2G.

Application Field of S-80913CNMC-G8HT2G

The S-80913CNMC-G8HT2G is specifically designed for applications involving power supply voltage monitoring, and it provides a wide operating temperature range from -40°C to +85°C. As a result, it is highly suitable for use in industrial electronic equipment and aerospace applications, where the temperatures can often reach extreme levels. The small 5-lead SOT23 package ensures maximum board space savings, which is often an important consideration in tight environments.

The overvoltage/undervoltage protection margin of the S-80913CNMC-G8HT2G is also an important factor in its application field. This IC has a 3.6V OVP/UVL trip level, 2.7V reset signal output, and 0.8V OVP/UVL hysteresis. The typical reset time delay is 140ms, reducing the possibility of inaccurate or delayed reset signals. Furthermore, the powerful protection circuitry ensures that the IC remains reliable in a wide variety of conditions.

Working Principles of S-80913CNMC-G8HT2G

The S-80913CNMC-G8HT2G combines two important technologies in its design. The first is the overvoltage protection (OVP) circuit. This circuit is responsible for monitoring the voltage of the power supply rail. When the voltage exceeds the predetermined OVP trip level set by the IC, the OVP circuit will immediately activate and send out a reset signal. This reset signal is designed to protect critical equipment or components from overvoltage damage.

The second technology in the S-80913CNMC-G8HT2G is the undervoltage protection (UVL) circuit. This circuit monitors the voltage of the power supply rail and will send out a reset signal if the voltage falls below the preset UVL trip level. This protects against damage caused by insufficient power supply voltage.

The IC also has some useful features designed to maximize system stability and reliability. There is an adjustable reset output delay option to prevent false or incorrect reset signals, adjustable output-low reset thresholds, power-on reset signals, and internal power-on reset generation. All of these additional features ensure that the IC is reliable and robust even in extreme operating conditions.

In conclusion, the S-80913CNMC-G8HT2G is a highly reliable and robust power monitoring IC. Its wide operating temperature range, adjustable reset output delay, and OVP/UVL circuitry ensure that it is suitable for use in many industrial and aerospace applications. Furthermore, its small SOT23 package offers maximum board space savings, making it an attractive choice for tight environments.
