MAX1608EEE+ datasheet by Maxim Integrated Products

MAX1608EEE+ Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the MAX1608EEE+?
  The MAX1608EEE+ requires careful layout and placement to ensure proper operation. It is recommended to place the device close to the battery, use short traces, and avoid routing sensitive analog signals near the device. A 4-layer PCB with a solid ground plane is recommended. Refer to the Maxim Integrated Products application note AN1890 for more details.
• How do I ensure the accuracy of the battery voltage measurement?
  To ensure accurate battery voltage measurement, it is essential to use a high-impedance input buffer, such as an op-amp, to buffer the battery voltage signal. Additionally, the PCB layout should be designed to minimize noise and interference. It is also recommended to use a low-pass filter to filter out high-frequency noise.
• What is the recommended input voltage range for the MAX1608EEE+?
  The recommended input voltage range for the MAX1608EEE+ is 2.5V to 5.5V. Operating the device outside of this range may affect its accuracy and reliability.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) functions?
  The MAX1608EEE+ has a built-in POR and BOR function. To handle these functions, it is recommended to connect the POR pin to a capacitor to ensure a clean power-on reset. The BOR function can be adjusted by connecting a resistor and capacitor to the BOR pin.
• What is the purpose of the EN pin, and how do I use it?
  The EN pin is an active-low enable input that allows the device to be shut down to conserve power. To use the EN pin, connect it to a logic signal that is high when the device is active and low when the device is in shutdown mode.
