Functional Features

• Monitors the voltage level at the TH pin and compares it with the internally set threshold voltage.
• Provides an active-low reset signal on the RESET# pin when the monitored voltage falls below the threshold.
• The threshold voltage can be adjusted using an external resistor divider connected to the TH pin.
• Includes a manual reset input (MR) that allows an immediate reset regardless of the monitored voltage level.

Advantages and Disadvantages

Advantages

• Low quiescent current makes it suitable for battery-powered applications.
• Adjustable threshold voltage allows flexibility in monitoring different voltage levels.
• Precision accuracy ensures reliable voltage monitoring.
• Small SOT23-8 package enables space-saving designs.

Disadvantages

• Limited supply voltage range (1.6V to 5.5V) may not be suitable for all applications.
• Active-low open-drain output requires an external pull-up resistor for proper signal level translation.

Working Principles

The MAX6365PKA26-T operates by comparing the voltage at the TH pin with the internally set threshold voltage. When the monitored voltage falls below the threshold, the active-low reset signal is asserted on the RESET# pin. The threshold voltage can be adjusted using an external resistor divider connected to the TH pin. The manual reset input (MR) allows an immediate reset regardless of the monitored voltage level.

Detailed Application Field Plans

The MAX6365PKA26-T is commonly used in various applications where voltage monitoring is critical. Some potential application fields include:

1. Battery-Powered Devices: Ensuring proper operation and preventing damage due to low battery voltage.
2. Power Supply Monitoring: Detecting power supply failures or abnormal voltage levels.
3. Industrial Control Systems: Providing reset signals for microcontrollers or other control circuitry.
4. Automotive Electronics: Monitoring voltage levels in automotive systems to prevent malfunctions.
