The ADM1085AKSZ-REEL7, developed by Analog Devices (ADI), is a high-precision digital power system monitor designed for real-time voltage, current, and temperature monitoring in industrial and server applications. This device integrates a 12-bit ADC, multiple voltage/current sensing channels, and a temperature sensor, enabling comprehensive system health monitoring. It operates from a supply voltage of 2.7V to 5.5V and communicates via I2C/SMBus, offering flexible integration into embedded systems. Encapsulated in a compact TSSOP-16 package, it supports a temperature range of -40°C to +125°C, ensuring reliability in harsh environments.

Key Features

• Multi-Channel Monitoring:
• Monitors 8 voltage channels (±2% accuracy) and 4 current channels (±3% accuracy) via shunt resistors.
• Integrates a local temperature sensor (±3°C accuracy) and supports remote diode temperature sensing (±1°C accuracy).
• High-Resolution ADC: 12-bit resolution for precise measurements of voltage, current, and temperature.
• Alarm and Fault Management:
• Configurable over/under-voltage, over-current, and over-temperature thresholds with interrupt outputs.
• Latched fault logging for post-event analysis.
• Low Power Consumption: Operates at 1.8mA active current and 50μA standby mode, ideal for energy-sensitive systems.
• Flexible Interface: I2C/SMBus compatible (100kHz to 400kHz) with address selection for multi-device daisy-chaining.
• Enhanced Safety: ESD protection (4kV HBM) and power-on reset (POR) functionality.
