常見問題解答

What is DS1647-120+?

The DS1647-120+ is a non-volatile controller, real-time clock (RTC), and power monitor device designed by Maxim Integrated. It combines the functions of a real-time clock, a calendar, and a power supply monitor in a single chip, making it suitable for applications such as network switches, routers, and servers.

How Does DS1647-120+ Work?

The DS1647-120+ operates by providing real-time clock and calendar functions to accurately track time and date in various applications. Additionally, it includes power monitoring capabilities to track voltage, current, and temperature, providing essential information for power management and system health monitoring.

How Many Pins does DS1647-120+ have and What are the Functions of the Pinout Configuration?

The DS1647-120+ is housed in a 28-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

  • VBAT: Battery input for backup power.
  • INT/SQW: Interrupt or square wave output.
  • SCL: Serial clock for I2C communication.
  • SDA: Serial data for I2C communication.
