Overview
The LM5066IPMHX/NOPB is a hot swap voltage controller designed by Texas Instruments. This device is tailored for robust protection and precision monitoring in systems operating within the 10 to 80 V range. It features a PMBus™ interface, making it compliant with Node Manager 2.0 and 3.0 command structures. The LM5066I provides comprehensive monitoring of voltage, current, power, and temperature, along with advanced protection mechanisms such as programmable undervoltage (UV), overvoltage (OV), and current limit (ILIM) thresholds. It also supports energy monitoring and has a 12-bit ADC with a 1-kHz sampling rate, enhancing system diagnostics and efficiency optimization.
