Working Principles

ADM1294-1AACPZ operates by continuously monitoring the power supply voltage, current, and temperature of each channel. It compares these values against user-programmable thresholds to detect any abnormal conditions. In case of an overvoltage, undervoltage, or overcurrent event, the device triggers an interrupt and reports the fault condition via the ALERT pin. The I2C/SMBus interface allows for easy configuration and retrieval of monitoring data.

Detailed Application Field Plans

ADM1294-1AACPZ finds applications in a wide range of electronic systems, including: - Server and data center power management - Industrial automation and control systems - Telecommunications equipment - Automotive electronics - Consumer electronics - Medical devices
