DS1804-050+ datasheet by Maxim Integrated Products

DS1804-050+ Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the DS1804-050+?
  The recommended operating voltage range for the DS1804-050+ is 2.7V to 5.5V, although it can operate down to 2.2V with reduced performance.
• How do I ensure reliable communication between the DS1804-050+ and the microcontroller?
  To ensure reliable communication, make sure to follow the I2C protocol guidelines, use pull-up resistors on the SCL and SDA lines, and ensure that the clock frequency is within the recommended range of 10 kHz to 400 kHz.
• What is the maximum current that the DS1804-050+ can sink or source?
  The DS1804-050+ can sink or source up to 3mA of current per output pin, although it's recommended to limit the current to 1mA or less to ensure reliable operation.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) features of the DS1804-050+?
  The POR and BOR features are enabled by default. To handle them, ensure that your microcontroller is designed to handle the reset signals generated by the DS1804-050+, and that your system is designed to recover from power-on and brown-out events.
• Can I use the DS1804-050+ in a noisy environment?
  Yes, the DS1804-050+ has built-in noise filtering and hysteresis on the input pins, making it suitable for use in noisy environments. However, it's still recommended to follow proper PCB design and layout practices to minimize noise and ensure reliable operation.
