ADI Hot-swap controller ADM1278-1ACPZ-RL power monitoring 1 Channel General Purpose
The ADM1278-1ACPZ-RL is a high-performance hot-swap controller and power monitor from Analog Devices, designed to provide safe board insertion and removal in high-availability systems. This IC integrates advanced current, voltage, and power monitoring capabilities, making it ideal for enterprise servers, telecom equipment, and storage systems. It supports a wide input voltage range of 4.5V to 16.5V, allowing it to manage power delivery in 12V intermediate bus architectures efficiently. The device features a precision 12-bit ADC for accurate real-time power measurements, enabling intelligent power management and fault protection.
The ADM1278-1ACPZ-RL incorporates a robust hot-swap controller with programmable current limiting, slew rate control, and fault protection to prevent damage from inrush currents during live insertion. It includes an integrated MOSFET gate driver to control external N-channel FETs, ensuring smooth power-up sequencing. The chip also provides comprehensive fault detection for overcurrent, undervoltage, and overtemperature conditions, enhancing system reliability. Communication is facilitated via a PMBus-compliant I²C interface, allowing for easy configuration and real-time telemetry monitoring.
