DESCRIPTION

· The RTQ6053 is a high-accuracy current-sense monitor with I2C and SMBus interfaces, providing full system information by reading load current and power.

· It monitors voltage drops across a sense resistor and BUS voltage, converting them into current (amperes) and power (watts) via an internal 16-bit ADC.

· Features include programmable calibration, adjustable conversion time, and averaging functions for design flexibility.

· Operates in a temperature range of -40°C to 125°C with an input voltage of 2.7V to 5.5V, and senses current on a common-mode bus voltage of 0V to 36V.

· Includes an alert function with open-drain output for over-current, over-voltage, and over-power warnings.

· Available in a compact VQFN-16L 3x3 package.

FEATURES

· I2C and SMBus compatible interface.

· Bi-directional current sensing for high-side or low-side applications.

· Operates with a supply voltage range of 2.7V to 5.5V.

· Monitors bus voltage from 0V to 36V.

· High accuracy with a maximum gain error of 0.3%.

· Low offset voltage, maximum 25µV.

· Reports current, bus voltage, and system power.
