After the MAX7301 is connected, its default status is input, so it is necessary to configure the 0x09-0x0F register in order to change the component to output mode. However, when designating the output pin, if the output current is too large, such that the power supply is unable to supply the necessary current, it will result in the output voltage dropping. Once the voltage drops to the 2.5V, the component will reset to input mode causing the aforementioned issue, so it is necessary to confirm if the power supply has sufficient drive power.
