RTQ6059

Bi-Directional Current and Power Monitor with I2C Interface for High-Side or Low-Side Measurement

The RTQ6059 is a high-accuracy current-sense monitor with an I²C and SMBus interface. The device provides full information for the system by reading the load current and power. The device monitors both the voltage drops across the sense resistor and the BUS voltage, converting them into the current in amperes and power in watts through an internal analog-to-digital converter ADC. The programmable calibration, adjustable conversion time, and an averaging function are also built in for more design flexibility. The RTQ6059 provides a wide operating temperature range from -40°C to 125C and operates with an input voltage range from 3V to 5.5V. The device can sense the current on common-mode bus voltages ranging from 0V to 32V. The RTQ6059 is available in a small 8-pin TSOT-23-8 (COL) package.
