RT6056

High-Side or Low-Side Measurement, Bi-Directional Current

and Power Monitor with 16 Bit ADC and Alert

General Description

The RT6056 is a high accuracy current-sense monitor

Features

⚫ I C and SMBUS Compatible Interface

⚫ Bi-Direction Current Sensing, Available for High-

Side or Low-Side Sensing

with an I C and SMBUS interface, and the device

provides full information for system by reading out the

load current and power.

⚫ 2.7V to 5.5V Operation Supply Voltage Range

⚫ Monitor Bus Voltage from 0V to 36V

⚫ High Accuracy, Max 0.12% Gain Error

⚫ Low Offset Voltage, Max 10V Offset

⚫ Current, Bus Voltage and System Power

Reporting

The device monitors both of the drops across sense

resistor and the BUS voltage, converts into the current

in amperes, and power in watts through internal analog-

to-digital converter ADC. The programmable calibration,

adjustable conversion time, and averaging function are

also built in for more design flexibility.

⚫ Programmable Warning Threshold

⚫ Over-Current, Over-Voltage and Over-Power Alert

⚫ MSOP-10 Package

The RT6056 provides a wide temperature environment

from −40C to 125C and operates with an input voltage

from 2.7V to 5.5V. The device senses the current on

common-mode bus voltage with 0V to 36V.

Applications

⚫ Servers, Storage and Network Equipment

⚫ Portable, Battery-Powered Systems

⚫ Point of Load (POL) Power Modules

⚫ Notebook Computers

The RT6056 also provides an alert function with open-

drain output, and it provides the full protection by giving

a warning to host from over-current, over-voltage and

over-power situation.

⚫ High End Digital TV

The RT6056 is available in a small MSOP-10 package.

The recommended junction temperature range is −40C

to 125C.
