MAX817LCSA+ datasheet by Maxim Integrated Products

MAX817LCSA+ Frequently Asked Questions (FAQs)

• What is the purpose of the delay pin on the MAX817LCSA+?
  The delay pin is used to set the time delay between the power-on reset (POR) and the output going high. This allows the system to stabilize before the microcontroller or processor is released from reset.
• How does the MAX817LCSA+ handle brownout detection?
  The MAX817LCSA+ has a built-in brownout detection feature that resets the output when the input voltage falls below a certain threshold (typically 1.8V). This ensures that the system is properly reset during a brownout condition.
• What is the recommended input capacitor value for the MAX817LCSA+?
  The recommended input capacitor value is 0.1uF to 1uF, depending on the specific application and noise requirements. A larger capacitor value can help filter out noise, but may also increase the startup time.
• Can the MAX817LCSA+ be used in a 3.3V system?
  Yes, the MAX817LCSA+ can be used in a 3.3V system. The device has a wide operating voltage range of 1.8V to 5.5V, making it suitable for 3.3V systems.
• How does the MAX817LCSA+ behave during power-down?
  During power-down, the MAX817LCSA+ output goes low, ensuring that the system is properly reset. The device also has a low quiescent current of 1.5uA, making it suitable for battery-powered systems.
