DESCRIPTION  
The TPS2482 and TPS2483 provide hotswap control

•
9-V to 36-V Input Range, 40 V Abs. Max  
Current, Voltage and Power Monitor  
and precision monitoring for 9-V to 36-V applications.  
Accurate voltage, current, and power monitoring is  
provided by a 16-bit A/D converter with a serial  
interface that is compatible with I2C and SMBus.  
Voltage and current measurements are interleaved  
and multiplied internally to provide concurrent power  
calculations. These devices have high current  
monitoring accuracy over temperature and a broad  
load range. This makes them well suited for  
applications where load identity and health is  
determined by current profile, such as remote radio  
heads or cellular antennae.  
±0.5% Accurate Current Monitoring

16 Programmable I2C™ Addresses  
Configurable Averaging Options  
Programmable MOSFET SOA protection  
High Side Gate Drive for External N-FET  
Programmable Fault Timer  
Open-Drain Power-Good Output  
20-Pin TSSOP Package  
The hotswap section drives N-channel MOSFETs,  
with timed inrush and fault-current limiting. Advanced  
MOSFET safe operating area (SOA) protection is  
achieved by programmable constant-power foldback

and  
a fixed current limit. This results in an  
exponential inrush current profile as shown in the  
start-up figure below. As VOUT ramps up and the VDS  
of the MOSFET is reduced the current increases  
keeping MOSFET power dissipation within its SOA at  
all times. The TPS2482 latches off after a hard fault,  
while the TPS2483 automatically attempts to restart  
after a cool-off delay.  
Plug-In Modules  
Base Station 24 V Antenna Power  
Industrial 24 V - 28 V Power  
The TPS2482 and TPS2483 can be dropped into  
existing TPS2480 and TPS2481 sockets to provide  
improved accuracy and operating voltage range. This  
can be accomplished with no PCB changes and  
minor software modifications.
