LM5064

Negative Voltage System Power Management and

Protection IC with PMBus

General Description

Features

The LM5064 combines a high performance hot swap con-

troller with a PMBus^TMcompliant SMBus/I²C interface to ac-

curately measure, protect and control the electrical operating

conditions of systems connected to a backplane power bus.

The LM5064 continuously supplies real-time power, voltage,

current, temperature and fault data to the system manage-

ment host via the SMBus interface.

Input voltage range: -10V to -80V

■

Programmable 26 mV or 50 mV current limit threshold with

power limiting (MOSFET power dissipation limiting)

Real time monitoring of V_IN, V_OUT, I_IN, P_IN, V_AUXwith 12-bit

resolution and 1 kHz sampling rate

■

Configurable circuit breaker protection for hard shorts

Configurable under-voltage and over-voltage protection

■

The LM5064 control block includes a unique hot swap archi-

tecture 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 LM5064 interfaces with a low-cost external diode

for monitoring the temperature of the external MOSFET or

other thermally sensitive components. The PGD output pro-

vides a fast indicator when the input and/or output voltages

are outside their programmed ranges.

Remote temperature sensing with programmable warning

and shutdown thresholds

Detection and notification of damaged MOSFET condition

Power measurement accuracy: ±4.5% over temperature

True input power averages dynamic power readings

■

Averaging of V_IN, I_IN, P_IN, and V_OUTover 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

I²C/SMBus interface and PMBus compliant command

structure

■

The LM5064 monitoring circuit computes both the real-time

and average values of subsystem operating parameters

(V_IN, I_IN, P_IN, V_OUT) 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.
