National Semiconductor Corp.’s two new high-voltage system power management and protection integrated circuits (ICs) feature on-chip power management bus (PMBus) support. The 48V input voltage LM5066 and -48V input voltage LM5064 integrate system protection and management blocks that precisely measure, control and manage the electrical operating conditions in systems such as routers, switches and base stations. The LM5066 and LM5064 enable comprehensive system power management for improving system reliability and reducing power consumption in wired and wireless telecom infrastructure systems that operate from high-voltage system backplanes. The LM5066 and LM5064 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.
