This IC is part of the PMIC - Supervisors category and is designed to provide robust reset and power monitoring capabilities for a wide range of electronic systems. Although marked as obsolete, the ADM1817-5ART-REEL7 remains a trusted solution for engineers seeking reliable voltage supervision in their designs. Below, we provide an in-depth analysis of its features, specifications, and applications to help you understand its value in modern electronics.

Detailed Features and Specifications

1. Simple Reset/Power-On Reset Functionality

The ADM1817-5ART-REEL7 ensures system stability by generating a reset signal during power-up or voltage drops. This feature is critical for preventing erratic behavior in microcontrollers and digital circuits, ensuring smooth operation even in fluctuating power conditions.

2. Single Voltage Monitoring

This IC monitors a single voltage rail (1V to 5V range), making it ideal for applications where only one power supply needs supervision. Its simplicity reduces design complexity and cost, perfect for compact and low-power systems.

3. Precision Voltage Threshold: 3.06V

The ADM1817-5ART-REEL7 triggers a reset when the monitored voltage falls below 3.06V, a threshold optimized for 3.3V systems. This precision ensures reliable performance without false triggers.

4. Push-Pull, Totem Pole Output

The push-pull output configuration with a totem pole structure delivers strong drive capability, ensuring clear and stable reset signals to downstream components like microprocessors or FPGAs.

5. Active High Reset Signal

With an active high reset polarity, the ADM1817-5ART-REEL7 aligns with the input requirements of most modern digital ICs, eliminating the need for additional inverters or level shifters.

6. Adjustable Reset Timeout: 100ms Minimum

The reset signal remains active for at least 100ms, providing ample time for system stabilization. This timeout period is configurable with external components for greater flexibility.

7. Wide Operating Temperature Range: -40 C to +105 C

Designed for harsh environments, this IC operates reliably across an industrial temperature range, making it suitable for automotive, industrial, and outdoor applications.

8. Surface-Mount Design (SOT-23-3 Package)

The compact SOT-23-3 package enables high-density PCB layouts and is compatible with automated assembly processes, reducing manufacturing costs.
