The MAX708CPA+ is a sensitive device and requires careful layout and placement to ensure proper operation. It is recommended to follow the layout guidelines provided in the datasheet, including keeping the device away from noise sources, using a solid ground plane, and minimizing trace lengths and widths.
The WDT should be disabled during power-up and power-down sequences to prevent unwanted resets. This can be done by pulling the WDT input low during these sequences. Additionally, the WDT should be re-enabled once the system is stable and running.
The manual reset input (MR) is used to reset the device and can be used to initiate a reset sequence. It should be pulled low for a minimum of 1.5 seconds to initiate a reset. The MR input should be connected to a push-button or other manual reset switch.
The MAX708CPA+ requires a stable power supply with a voltage range of 2.7V to 5.5V. The power sequencing requirements are critical, and it is recommended to follow the power-up and power-down sequences outlined in the datasheet to ensure proper operation.
The MAX708CPA+ has a maximum junction temperature of 150°C. Proper thermal management is critical to ensure reliable operation. This can be achieved by using a heat sink, ensuring good airflow, and minimizing thermal resistance between the device and the PCB.
