ADM1815-R23ARTZ-RL

Product Overview

Category

The ADM1815-R23ARTZ-RL belongs to the category of voltage supervisors and monitors.

Use

It is used to monitor the power supply voltage level and provide a reset signal to the microcontroller or other digital systems in the event of a power failure or voltage drop.

Characteristics

• Package: SOT-23
• Essence: Voltage supervisor with manual reset input
• Packaging/Quantity: Tape & Reel (3000 units per reel)

Specifications

• Voltage Threshold: 2.3V
• Reset Timeout Period: 140ms
• Operating Temperature Range: -40°C to 85°C
• Supply Voltage Range: 1.8V to 5.5V

Detailed Pin Configuration

1. VDD (Supply Voltage)
2. GND (Ground)
3. MR (Manual Reset Input)
4. RESET (Active-Low Reset Output)

Functional Features

• Monitors supply voltage and asserts reset when it falls below the threshold
• Manual reset input for external system control
• Low supply current of 6µA (typical)

Advantages and Disadvantages

Advantages

• Small package size
• Wide operating voltage range
• Low power consumption

Disadvantages

• Fixed voltage threshold may not be suitable for all applications

Working Principles

The ADM1815-R23ARTZ-RL continuously monitors the supply voltage. When the voltage drops below the preset threshold, the reset output is asserted. The manual reset input allows external control over the reset function.

Detailed Application Field Plans

This device is commonly used in embedded systems, IoT devices, and battery-powered applications where maintaining proper system operation during varying supply voltages is critical.

Detailed and Complete Alternative Models

• ADM1815-5ARTZ-RL: 5V voltage threshold
• ADM1815-10ARTZ-RL: 10V voltage threshold
• ADM1815-3.3ARTZ-RL: 3.3V voltage threshold

In conclusion, the ADM1815-R23ARTZ-RL is a compact and efficient voltage supervisor suitable for various low-power applications, providing reliable monitoring and reset functionality.
