The RTQ6053/RTQ6053B is a high-accuracy current-sense monitor featuring I2C and SMBus interface, providing comprehensive system information by reading both load current and power.The device monitors the voltage drop across sense resistor and the BUS voltage, converting these measurements into current in amperes and power in watts through internal analog-to-digital converter (ADC). Programmable calibration, adjustable conversion time, and an averaging function are integrated to offer enhanced design flexibility. The RTQ6053/RTQ6053B operates over a wide temperature range from -40°C to 125°C and supports an input voltage from 2.7V to 5.5V. The device is capable of sensing current on a common-mode bus voltage from 0V to 36V.An open-drain alert output is provided for system protection, enabling the host to receive warnings in the event of overcurrent, overvoltage, or overpower conditions.The RTQ6053/RTQ6053B is available in a compact VQFN-16L 3x3 package.
