PMIC, or power management integrated circuit, is a type of powered electronic device commonly used in modern electronic systems. Although these devices are mainly used to manage the power levels in various electronic devices, they are also used to provide various control and supervision functions. The DS1231-35+ is an example of such a supervisor device. It provides two separate power monitors and four supervised output channels, along with Low Voltage Detection/Power Fail/System Reset signal output options. In this article, we will focus on the DS1231-35+’s application field and working principles.
Operating Voltage
Before looking into the application field and working principles of the DS1231-35+, the operating voltage must first be discussed. It requires a voltage input of 2.3V to 6.0V and has a maximum quiescent current of 4.8mA. This operating voltage allows the device to be used with a wide range of applications and electrical environments, making it an ideal choice for many systems. It is also important to note that the device has an operating temperature range of -40 to +85C, allowing it to work even in extreme environmental conditions.
Overview of Application Field and Working Principle
The DS1231-35+ can be used in a variety of applications, including industrial automation, automotive applications, consumer electronics, and more. The device is designed to supervise and control power in various types of electronic systems, providing a reliable solution for these applications. In terms of the working principle, the device provides two outputs for power supply monitoring and four supervised output channels for systems control. It also includes two Low Voltage Detection (LVD) and/or Power Fail (PF) input pins, along with a System Reset (SR) signal output pin.
The two outputs for power supply monitoring are used to monitor the power supply of the system. When a fault condition is detected, an output signal is sent, which can be used to trigger an appropriate action. On the other hand, the four supervised output channels provide a reliable solution for systems control. For instance, they can be used to control the operation of a fan, a lamp, or other devices. The LVD/PF inputs are used to detect low voltage and/or power failures, while the SR output pin is used to trigger a system reset when necessary.
Other Key Features
The DS1231-35+ has several additional features that make it even more useful. One example is the built-in watchdog timer, which is used to ensure that the system’s operation is uninterrupted. The device also includes an overvoltage detector and a voltage comparator, which can be used to detect abnormal conditions and take corrective measures. Additionally, it has a fully programmable reset delay time, which can be set to a range of up to 30 seconds, allowing the user to customize the system’s response time.
Conclusion
Overall, the DS1231-35+ is a versatile and reliable power management integrated circuit. Its application field and working principles have been discussed, and it has been shown to be a useful tool for managing and controlling various types of electronic systems. Additionally, its additional features, such as the watchdog timer, the overvoltage detector and voltage comparator, and the programmable reset delay time, make it even more useful in achieving reliable system operation.
