−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 (TJ) 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.
