Application field of DS1817-5+T&R

DS1817-5+T&R is a very versatile PMIC - Supervisor. It has a wide range of applications in the field of industrial control and electronics. Its main functions include voltage monitoring, voltage trip-point accuracy, system reset, power-on reset and reset management.

DS1817-5+T&R is suitable for a variety of applications. It is often used in storage, instrumentation, switching power supply, UPS, computer, distributed control system, automotive and avionics products, as well as other dangerous applications that require higher accuracy and reliability. It can also be used in failure detection, power supply filtering, debugging, prevention of power-on reset, voltage monitoring and reset management in industrial control systems.

Working principle of DS1817-5+T&R

DS1817-5+T&R is composed of power monitors and reset controllers. Its working principle is as follows: firstly, it will detect the voltage of system and generate the trip-points. Secondly, the power monitor can generate CPU reset pulse when the voltage of system is below the threshold value. Thirdly, when the voltage exceeds the upper threshold, a reset pulse will also be generated. Finally, there will be a reset signal output at the Reset port.

In addition, DS1817-5+T&R has a pre-charge feature. It provides a more reliable power-on reset signal output and reduces the current consumption of the system. At the same time, the chip can protect the system from the risk of reset failure, and the reset signal can be closely monitored.

In addition, DS1817-5+T&R has several configurable pins to set different threshold values and time delays. The chip can detect the power supply voltage accurately and detect the input signal from the Reset pin. It also has a signal output pin to control the switch element and reset the system quickly and reliably.

DS1817-5+T&R also has many functions such as configurable reset delay, active and inactive reset signal options, a start pin for controlling the reset function and an interlock function for reset signal protection.

Overall, DS1817-5+T&R is a powerful and reliable PMIC - Supervisor. It has a wide range of applications in industrial control and electronics, as well as excellent features and functions, making it an ideal choice for many projects.
