MAX811REUS+ datasheet by Maxim Integrated Products

MAX811REUS+ Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the MAX811REUS+?
  The MAX811REUS+ requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
• How do I handle the startup sequence for the MAX811REUS+?
  The MAX811REUS+ has a specific startup sequence that must be followed to ensure proper operation. The sequence is: 1) Apply VCC, 2) Apply VIN, and 3) Apply EN. This sequence ensures that the internal voltage regulators are powered up correctly and that the device is properly initialized.
• What is the maximum input voltage that the MAX811REUS+ can handle?
  The MAX811REUS+ can handle input voltages up to 28V, but it is recommended to operate within the specified range of 4.5V to 16V for optimal performance and reliability.
• How do I determine the output voltage of the MAX811REUS+?
  The output voltage of the MAX811REUS+ is determined by the resistive divider network connected to the FB pin. The output voltage can be calculated using the formula: VOUT = 1.25V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the purpose of the EN pin on the MAX811REUS+?
  The EN (enable) pin is used to turn the MAX811REUS+ on and off. When EN is high, the device is enabled and operates normally. When EN is low, the device is disabled and enters a low-power shutdown mode.
