Key Featrues
±0.3% Accurate 12-bit ADC: The ADM1278 features a highly accurate 12-bit analog-to-digital converter (ADC) that measures current, voltage, power, and temperature. This precision ensures reliable monitoring and control, enhancing system performance and enabling accurate power budgeting in applications like servers and telecommunications equipment.
320 ns Short Circuit Response Time: With a rapid 320 ns response time to short circuits, the ADM1278 provides robust protection for connected devices. This quick reaction minimizes potential damage and downtime, improving system reliability and safety in high-demand environments.
FET Health Fault Detection and Shutdown: The controller monitors the health of the external FET and initiates a shutdown if a fault is detected. This feature prevents catastrophic failures, extends the lifespan of components, and ensures safe operation in critical systems.
Constant Power Foldback for FET SOA Protection: The constant power foldback feature ensures tighter protection of the FET's safe operating area (SOA). This enhances efficiency and reliability by preventing overheating and damage during high-load conditions, making it ideal for power-intensive applications.
