DS28E22Q+T Frequently Asked Questions (FAQs)

  • The DS28E22Q+T 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.
  • The DS28E22Q+T has a built-in voltage regulator that can operate down to 2.5V, and it can also tolerate voltage drops or brownouts on the 1-Wire bus. However, the device may reset or enter a low-power state if the voltage drop is severe or prolonged.
  • Yes, the DS28E22Q+T has a high-accuracy bandgap voltage reference and a precision temperature sensor, making it suitable for applications that require high accuracy and stability, such as industrial automation, medical devices, and aerospace.
  • The DS28E22Q+T has built-in EMI and RFI protection, including a 1-Wire bus filter and a shielded package, to minimize the effects of electromagnetic interference and radio-frequency interference.
  • Yes, the DS28E22Q+T is designed to operate in harsh environments, with a temperature range of -40°C to +85°C and a humidity range of 5% to 95% RH. However, the device may require additional protection or shielding in extreme environments.
