Pin Configuration

The MAX6389LT26D6+T has the following pin configuration:

1. GND: Ground connection
2. MR: Manual reset input
3. VCC: Power supply voltage input
4. RESET: Reset output
5. TH: Threshold adjust input
6. NC: No connection

Functional Features

• Accurate voltage monitoring: The MAX6389LT26D6+T continuously monitors the power supply voltage and compares it to the user-adjustable threshold.
• Adjustable reset threshold: The threshold voltage can be set using an external resistor divider connected to the TH pin.
• Reset signal generation: When the monitored voltage falls below the threshold, the MAX6389LT26D6+T asserts the RESET pin, indicating a reset condition.
• Manual reset input: The MR pin allows for manual resetting of the device, overriding the voltage monitoring function.

Advantages and Disadvantages

Advantages: - Low-power operation: The MAX6389LT26D6+T consumes only 3µA of quiescent current, making it suitable for battery-powered applications. - Adjustable threshold: The user can set the desired voltage threshold to trigger the reset signal. - Small package size: The 6-pin Thin SOT23 package offers space-saving benefits in compact designs.

Disadvantages: - Fixed reset timeout period: The reset timeout period is fixed at 140ms and cannot be adjusted. - Limited temperature range: The operating temperature range of -40°C to +85°C may not be suitable for extreme environments.

Working Principles

The MAX6389LT26D6+T operates by continuously monitoring the power supply voltage using an internal voltage reference. The TH pin allows the user to adjust the threshold voltage by connecting an external resistor divider. When the monitored voltage falls below the threshold, the RESET pin is asserted, indicating a reset condition. The reset signal remains active for the fixed timeout period of 140ms, after which it is automatically released.

Detailed Application Field Plans

The MAX6389LT26D6+T is commonly used in various applications where accurate voltage monitoring and reset functionality are required. Some potential application fields include:

1. Battery-powered devices: The low-power operation and adjustable threshold make it suitable for battery-powered devices that require reliable voltage monitoring and reset capabilities.
2. Microcontroller systems: The MAX6389LT26D6+T can be used to ensure proper system initialization and prevent erratic behavior in microcontroller-based systems.
3. Industrial control systems: It can be employed in industrial control systems to monitor power supply voltages and initiate system resets in case of voltage fluctuations or failures.
