4. VCC: Power supply input
5. RESET: Reset output

Functional Features

• Voltage monitoring: Monitors the input voltage and compares it with the preset threshold voltage.
• Reset generation: Generates a reset signal when the input voltage falls below the threshold voltage.
• Manual reset: Allows for manual reset by asserting a low level on the MR pin.
• Power-on reset delay: Provides a fixed delay period after power-up before generating the reset signal.
• Active-low reset output: The RESET pin goes low when a reset condition is detected.

Advantages and Disadvantages

Advantages

• Small package size allows for space-saving designs.
• Low power consumption prolongs battery life in portable devices.
• Wide operating temperature range enables usage in various environments.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• Limited reset timeout period may not be suitable for certain applications requiring longer timeouts.
• Single threshold voltage may not cater to all voltage monitoring requirements.

Working Principles

MAX6389XS28D1+ operates by continuously monitoring the input voltage. When the voltage falls below the preset threshold, the IC generates a reset signal. The reset signal remains active until the voltage rises above the threshold or a manual reset is asserted.
