Resistor networks and arrays have become increasingly popular today, thanks to the short circuit protection they offer and the low power consumption they allow. The Y4485V0157QT9R is a device from such a family. In this article, we’ll discuss its application fields and working principle.

Overview

The Y4485V0157QT9R is a resistor array that is widely used in industrial, consumer, and automotive applications. This device has an operating voltage range of 7 V to 100 V, and a power dissipation rating of 0.15 W. It is comprised of three resistors which are connected in series or in parallel depending on the mode selected. This resistor network can be used to reduce voltage spikes, provide short circuit protection, or provide current stability.

Applications

The Y4485V0157QT9R is commonly used in applications where a low voltage, low power resistor is required. It can be used to provide short circuit protection or reduce voltage spikes, such as in power supplies. It is also used to provide current stability in automotive applications, such as in fuel injectors and sensors. Additionally, this device can be employed in consumer applications such as cell phones and other portable electronic devices.

Working Principle

The Y4485V0157QT9R is a resistive voltage divider. This means that the three resistors in this network are connected in series, with each resistor having a different resistance value. The resistors act as a low power voltage divider, which reduces the voltage level of the input signal. The amount of voltage reduction depends on the resistor values, which are selected depending on the desired output voltage.

The Y4485V0157QT9R also features a short circuit protection mode. In this mode, the three resistors in the network are connected in parallel. This reduces the overall resistance value of the network, meaning the input voltage is not significantly reduced. Instead, this mode is used to reduce current spikes, allowing the device to safely handle current overloads.

Conclusion

The Y4485V0157QT9R is a versatile resistor array that is designed for use in low voltage, low power applications. It offers short circuit protection, voltage reduction, and current stability. This device is widely used in industrial, consumer, and automotive applications, making it a useful addition to any project or circuit.
