• Quiescent Current: 2µA (typical)

Detailed Pin Configuration

The MAX813LEUA+T has three pins:

1. GND: Ground pin
2. TRIP: Input pin for setting the voltage threshold
3. RESET: Output pin that goes low when the monitored voltage falls below the threshold

Functional Features

• Monitors the voltage level of a power supply or battery
• Provides a digital output signal indicating whether the voltage is above or below the set threshold
• Adjustable threshold voltage allows customization for different applications
• Low quiescent current minimizes power consumption
• Wide supply voltage range enables compatibility with various systems

Advantages and Disadvantages

Advantages: - Precise voltage monitoring - Low power consumption - Adjustable threshold for flexibility - Small package size for space-constrained designs

Disadvantages: - Limited to voltage monitoring only - Requires an external microcontroller or circuitry to take action based on the output signal

Working Principles

The MAX813LEUA+T operates by comparing the input voltage at the TRIP pin with the threshold voltage set by the user. When the input voltage falls below the threshold, the RESET pin goes low, indicating a power failure or low battery condition. The device continuously monitors the voltage and updates the output accordingly.

Detailed Application Field Plans

The MAX813LEUA+T finds applications in various fields, including:

1. Battery-powered devices: It can be used to monitor battery voltage and trigger actions when the battery is low.
2. Power supply monitoring: It ensures that the voltage supplied to critical components remains within the desired range.
3. Industrial control systems: It provides voltage monitoring for equipment and triggers alarms or shutdowns in case of power failures.
