Detailed Pin Configuration

MAX810SQ293D2T1G has a SOT-23-3 package with three pins:

1. VCC: Connects to the positive supply voltage.
2. GND: Connects to the ground or negative supply voltage.
3. RESET: Output pin that asserts a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the power supply voltage and provides a reset signal when it drops below the threshold.
• Active high or active low reset output options.
• Adjustable threshold voltage for flexibility in different applications.
• Low quiescent current consumption for power-sensitive designs.
• Precision voltage monitoring for accurate detection of voltage variations.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Adjustable threshold voltage enables customization for specific requirements. - Low power consumption prolongs battery life in portable devices. - Precision voltage monitoring ensures reliable operation.

Disadvantages: - Limited reset timeout period may not be suitable for all applications. - SOT-23-3 package may require additional precautions during assembly.

Working Principles

MAX810SQ293D2T1G operates by comparing the supply voltage with a reference threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating a power failure or unstable voltage condition. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

• Embedded Systems: MAX810SQ293D2T1G can be used in microcontroller-based systems to ensure proper operation during power fluctuations.
• Industrial Control: It is suitable for monitoring power supplies in industrial control systems, preventing malfunctions due to voltage variations.
• Automotive Electronics: The voltage supervisor can enhance the reliability of automotive electronics by providing reset signals during voltage dips or spikes.
• Battery-Powered Devices: MAX810SQ293D2T1G helps protect battery-powered devices from unexpected shutdowns caused by low voltage conditions.
