• Generates a reset signal when the voltage falls below the threshold voltage.
• Offers an adjustable reset timeout period to accommodate different system requirements.
• Provides a manual reset input for immediate system restart if needed.

Advantages and Disadvantages

Advantages: - Compact and space-saving SOT23-5 package. - Wide supply voltage range allows compatibility with various power sources. - Adjustable reset timeout period for flexibility in system design. - Manual reset input provides additional control.

Disadvantages: - Limited threshold voltage options may not suit all applications. - Not suitable for high-voltage applications (above 5.5V).

Working Principles

The MAX6388XS41D2-T operates by continuously monitoring the voltage level of the power supply connected to the VCC pin. When the voltage falls below the threshold voltage set by the TH pin, the circuit generates a reset signal on the RESET pin. The reset signal remains active until the voltage rises above the threshold voltage or a manual reset is applied to the MR pin. The reset timeout period can be adjusted using external components.
