The LM5066Hx provides robust protection and precision monitoring for 12V, 24V and 48V systems with programmable UV, OV, ILIM, and fast short-circuit protection for customized input power applications. Programmable power limit threshold along with adjustable fault timer (tFAULT) limits maximum power dissipation and ensures FET SOA protection under all conditions including startup and fault events. Two level overcurrent blanking with digital timers allows higher load transients to pass, enabling lower current limit settings and reducing requirements for strong SOA MOSFETs.
An integrated PMBus® interface enables remote monitoring, control, and configuration of the system in real time. Key parameters can be accessed remotely for telemetry, and various thresholds can be configured through PMBus or stored in internal EEPROM. The fast, accurate analog load current monitor supports predictive maintenance and dynamic power management including Intel PSYS and PROCHOT functionality to optimize server performance. A blackbox fault recording feature helps in debugging field failures.
The LM5066H2 features dual gate drive architecture which enables use of a single strong SOA FET to handle power stress during startup and fault conditions, combined with multiple small low RDS(ON) FETs for normal load current operation, reducing the total solution size. The devices are characterized for operation over a junction temperature range of –40°C to +125°C.
