−48 V Hot Swap Controller and Digital

Power Monitor with PMBus Interface

Data Sheet

ADM1075

FEATURES

PRODUCT HIGHLIGHTS

Constant power foldback for FET SOA protection

Precision (<1.0%) current and voltage measurement

Controls inrush and faults for negative supply voltages

Suitable for wide input range due to internal shunt regulator

25 mV/50 mV full-scale sense voltage

Fine tune current limit to allow use of standard sense resistor

Soft start inrush current limit profiling

1% accurate UVH and OV pins, 1.5% accurate UVL pin

PMBus/I²C interface for control, telemetry, and fault

recording

1. Constant Power Foldback.

Maximum FET power set by a PLIM resistor divider. This

eases complexity when designing to maintain FET SOA.

2. Adjustable Current Limit.

The current limit is adjustable via the ISET pin allowing for

the use of a standard value sense resistor.

3. 12-Bit ADC.

Accurate voltage, current, and power measurements. Also

enables calculation of energy consumption over time.

4. PMBus/I²C Interface.

PMBus fast mode compliant interface used to read back

status and data registers and set warning and fault limits.

5. Fault Recording.

Latched status registers provide useful debugging infor-

mation to help trace faults in high reliability systems.

6. Built-In Soft Start.

28-lead LFCSP and TSSOP

−40°C to 105°C junction temperature (T_J) operating range

APPLICATIONS

Telecommunication and data communication equipment

Central office switching

−48 V distributed power systems

Negative power supply control

High availability servers

Soft start capacitor controls inrush current profile with

di/dt control.
