DS28E25+ Frequently Asked Questions (FAQs)

  • The DS28E25+ can support up to 256 devices on a single 1-Wire bus, but the actual number of devices that can be connected depends on the specific application and the bus capacitance. It's recommended to limit the number of devices to 64 or less to ensure reliable operation.
  • The DS28E25+ has a built-in voltage regulator that can tolerate power supply noise and voltage drops. It can operate with a supply voltage range of 2.8V to 5.25V, and it has a low dropout voltage of 0.5V. However, it's still recommended to use a high-quality power supply and decoupling capacitors to ensure reliable operation.
  • Yes, the DS28E25+ is rated for operation up to 125°C, making it suitable for high-temperature applications. However, the device's accuracy and reliability may be affected at extreme temperatures, so it's recommended to consult the datasheet and perform thorough testing before using it in such applications.
  • The DS28E25+ has a built-in SHA-256 engine that provides secure authentication and data integrity. It also has a unique 64-bit ROM ID that can be used to identify the device and prevent counterfeiting. Additionally, the device supports advanced security features such as ECDSA and HMAC, making it suitable for secure applications.
  • Yes, the DS28E25+ is designed to be low-power and can be used in battery-powered devices. It has a low active current of 1.5mA and a standby current of 1.5μA, making it suitable for battery-powered applications. However, it's recommended to consult the datasheet and perform power consumption analysis to ensure that the device meets the power requirements of the application.
