[85V High-Voltage Direct Connection] A wide common-mode voltage range, supporting -20V to 85V, allows direct use in industrial systems operating at 12V/24V/48V/60V, and even higher voltages, without the need for any level conversion circuitry! [Full-Parameter Accurate Monitoring] A single chip simultaneously measures current, bus voltage, power, and temperature with high precision, providing key data for energy management. [Built-in Real-Time Power Calculation] An internal hardware multiplier calculates power values in real time, directly outputting the actual value, significantly reducing the burden on the MCU and improving system responsiveness and reliability. [Interrupt Function] Programmable threshold comparators trigger an ALERT interrupt when current, voltage, power, or temperature exceed specified limits, enabling rapid system protection and intelligent control. [I2C Interface with Multiple Addresses] Standard I2C communication supports logic levels from 1.8V to 5.5V. Multiple address options are available, allowing multiple chips to be connected to a single bus for easy expansion.
