LM25066A  
System Power Management and Protection IC with  
PMBus™  
I2C/SMBus interface and PMBus compliant command  
structure  
Programmable 25mV or 46mV current limit threshold  
Configurable circuit breaker protection for hard shorts  
General Description  
The LM25066A combines a high performance hot-swap con-  
troller with a PMBuscompliant SMBus/I2C interface to ac-  
curately measure, protect and control the electrical operating  
conditions of computing and storage blades connected to a  
backplane power bus. The LM25066A continuously supplies  
real-time power, voltage, current, temperature and fault data  
to the system management host via the SMBus interface.  
Configurable under-voltage and over-voltage lockouts  
with hysteresis  
Remote temperature sensing with programmable warning  
and shutdown thresholds  
Detection and notification of damaged MOSFET condition  
The LM25066A control block includes a unique hot-swap ar-  
chitecture that provides current and power limiting to protect  
sensitive circuitry during insertion of boards into a live system  
backplane, or any other "hot" power source. A fast acting cir-  
cuit breaker prevents damage in the event of a short circuit  
on the output. The input under-voltage and over-voltage lev-  
els and hysteresis are configurable, as well as the insertion  
delay time and fault detection time. A temperature monitoring  
block on the LM25066A interfaces with a low-cost external  
diode for monitoring the temperature of the external MOSFET  
or other thermally sensitive components. The POWER GOOD  
output provides a fast indicator when the input and/or output  
voltages are outside their programmed range. LM25066A  
current measurement accuracy is ±1% over temperature.  
Real time monitoring of VIN, VOUT, IIN, PIN, VAUX with 12-bit  
resolution and 1 kHz sampling rate  
Current measurement accuracy: ±1% over temperature  
Power measurement accuracy: ±2% over temperature  
True input power measurement using simultaneous  
sampling of VIN and IIN accurately averages dynamic  
power readings  
Averaging of VIN, IIN, PIN, and VOUT over programmable  
interval ranging from 0.001 to 4 seconds  
Programmable WARN and FAULT thresholds with  
SMBA notification  
Black box capture of telemetry measurements and device  
status triggered by WARN or FAULT condition  
The LM25066A monitoring block computes both the real-time  
and average values of subsystem operating parameters  
(VIN, IIN, PIN, VOUT) as well as the peak power. Accurate power  
averaging is accomplished by averaging the product of the  
input voltage and current. A black box (Telemetry/Fault Snap-  
shot) function captures and stores telemetry data and device  
status in the event of a warning or a fault.  
24-lead LLP package  
Applications  
Server backplane systems  
Basestation power distribution systems  
Solid state circuit breaker
