RTQ6056 New Product

Update Alert Share

The RTQ6056 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 RTQ6056 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 RTQ6056 also provides an alert function with open-drain output, and it provides the full protection by giving a warning to host in over-current, over-voltage and over-power situations.

The RTQ6056 is available in a small MSOP-10 package.
