MAX77812AEWB+T datasheet by Maxim Integrated Products

MAX77812AEWB+T Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the MAX77812AEWB+T?
  The recommended PCB layout for the MAX77812AEWB+T can be found in the Maxim Integrated Products' application note AN5359, which provides guidelines for PCB layout, component placement, and thermal management to ensure optimal performance and reliability.
• How do I configure the I2C address of the MAX77812AEWB+T?
  The I2C address of the MAX77812AEWB+T can be configured by connecting the ADDR pin to VCC, GND, or leaving it open. The address can be set to one of four possible values: 0x1A, 0x1B, 0x1C, or 0x1D, depending on the ADDR pin configuration.
• What is the maximum input voltage that the MAX77812AEWB+T can handle?
  The MAX77812AEWB+T can handle input voltages up to 5.5V, but it is recommended to operate within the specified input voltage range of 3.5V to 5V for optimal performance and reliability.
• How do I implement overvoltage protection (OVP) with the MAX77812AEWB+T?
  The MAX77812AEWB+T has a built-in OVP feature that can be enabled by connecting the OVP pin to VCC. When the input voltage exceeds the OVP threshold (typically 5.5V), the device will shut down to protect itself and the system from damage.
• What is the typical quiescent current (IQ) of the MAX77812AEWB+T?
  The typical quiescent current (IQ) of the MAX77812AEWB+T is around 1.5mA, but this value can vary depending on the operating conditions, such as input voltage, output voltage, and load current.
