Pin Description: 1. GND: Ground connection. 2. MR: Manual reset input. Pulling this pin low forces a reset. 3. VCC: Power supply input. 4. RESET: Reset output. Goes low when the monitored voltage falls below the threshold. 5. TH: Threshold voltage selection pin. Connect to VCC or GND to set the desired threshold voltage.

Functional Features

• Monitors the voltage level of the power supply continuously.
• Generates a reset signal when the voltage falls below the set threshold.
• Provides a manual reset option through the MR pin.
• Offers multiple threshold voltage options for flexibility.
• Low power consumption.
• Small form factor for space-constrained applications.

Advantages and Disadvantages

Advantages: - Ensures reliable operation of electronic systems by resetting them during power supply issues. - Compact package allows for easy integration into various designs. - Multiple threshold voltage options provide flexibility for different applications. - Low power consumption helps in energy-efficient designs.

Disadvantages: - Limited to voltage monitoring and reset functionality, may not suit all system requirements. - SOT23-5 package may require additional considerations for heat dissipation.

Working Principles

The MAX6413UK26+T operates by continuously monitoring the voltage level of the power supply connected to the VCC pin. It compares the voltage with the set threshold voltage provided through the TH pin. When the voltage falls below the threshold, the RESET pin goes low, indicating a power supply issue. Additionally, the MR pin can be pulled low manually to force a reset.
