Max Current, Voltage and Power Monitor ±0.5% Accurate Current Monitoring ( -25°C < TJ < 85°C) 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 APPLICATIONS RRH (Remote Radio Heads) Storage Networks Plug-In Modules Base Station 24 V Antenna Power Industrial 24 V - 28 V Power DESCRIPTION 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 consta...
