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

and Power Monitor with 16-Bit ADC Op Amp/Alert

General Description

The RT6056 is a high accuracy current-sense monitor

with an I2C and SMBUS interface, and the device

provides full information for system by reading out the

load current and power.

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.

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.

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.

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