MAX708TCUA+ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the MAX708TCUA+?
  The recommended power-up sequence is to apply VCC first, followed by VBAT. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure that the MAX708TCUA+ is in a low-power state during shutdown?
  To ensure low power consumption during shutdown, make sure to set the SHDN pin high and the RST pin low. This will put the device in a low-power state, reducing current consumption.
• What is the purpose of the RST pin, and how do I use it?
  The RST pin is an active-low reset input that can be used to reset the device. To use it, pull the RST pin low for at least 100 ns to reset the device. This can be useful for initializing the device or recovering from an error state.
• How do I configure the watchdog timer on the MAX708TCUA+?
  The watchdog timer can be configured by writing to the WDT control register. The watchdog timer can be enabled or disabled, and the timeout period can be set to one of several predefined values.
• What is the purpose of the VBAT pin, and how do I use it?
  The VBAT pin is a backup power input that allows the device to retain its state during power failures. Connect a battery or a capacitor to the VBAT pin to provide backup power to the device.
