The TPS2482 and TPS2483 provide hotswap control 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.

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.

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.

While the standard monitoring function is limited to 36 V, with a few external components it is possible to monitor buses as high as 80 V. See special application description in High Voltage Application Example.
