National claims first with high voltage hot swap controllers
National Semiconductor has introduced what it claims are the industry's first high voltage system power management and protection ICs with on-chip PMBus support.
The 48V input voltage LM5066 and -48V input voltage LM5064 integrate system protection and management blocks that measure, control and manage the electrical operating conditions in systems such as routers, switches and base stations.
National says they provide complete subsystem power management for high voltage systems by precisely measuring the power to each card or block, while continuously protecting against damaging inrush current surges due to hot swap or transient events that damage downstream components.
The new ICs leverage National's hot swap architecture, which is designed to continuously monitor and limit both system current and power while measuring power consumption and fault conditions. They are designed to continuously supply the system management host with real time power, voltage, current, temperature and fault data for each node in the system.
