36-V Hotswap Controller with Precision I²C Power Monitoring

Check for Samples: TPS2482, TPS2483

FEATURES

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

( -25°C < T_J< 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

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

APPLICATIONS

RRH (Remote Radio Heads)

Storage Networks

and

a fixed current limit. This results in an

exponential inrush current profile as shown in the

start-up figure below. As V_OUTramps up and the V_DS

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.
