MAX6969AWG+ datasheet by Maxim Integrated Products

MAX6969AWG+ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX6969AWG+?
  The recommended PCB layout for the MAX6969AWG+ involves placing the device near the power source, using a solid ground plane, and keeping the input and output traces short and wide to minimize noise and EMI.
• How do I ensure the MAX6969AWG+ is properly powered on and off?
  To ensure proper power-on and power-off sequencing, connect the enable pin (EN) to a logic-level signal, and ensure that the input voltage (VIN) is stable and within the recommended range before enabling the device.
• What is the maximum output current capability of the MAX6969AWG+?
  The maximum output current capability of the MAX6969AWG+ is 1.5A per channel, but it's recommended to derate the output current based on the ambient temperature and the device's thermal characteristics.
• How do I protect the MAX6969AWG+ from overvoltage and undervoltage conditions?
  To protect the MAX6969AWG+ from overvoltage and undervoltage conditions, use a voltage supervisor or a voltage monitor to detect and respond to out-of-range input voltages, and consider adding overvoltage protection (OVP) and undervoltage protection (UVP) circuits.
• What is the recommended input capacitor value and type for the MAX6969AWG+?
  The recommended input capacitor value for the MAX6969AWG+ is 10uF to 22uF, with a low-ESR ceramic or tantalum capacitor type, placed as close to the device as possible to minimize noise and ripple.
