LM5056APMHE/NOPB Descrizione generale

Featuring a blend of high-performance analog and digital technology, the LM5056APMHE/NOPB is a versatile product designed to accurately measure the electrical operating conditions of systems connected to a backplane power bus. Equipped with a PMBus compliant SMBus™ and I²C interface, this device continuously supplies real-time power, voltage, current, temperature, and fault data to the system management host. The monitoring block within the LM5056APMHE/NOPB computes both real-time and average values of critical subsystem operating parameters such as input voltage, input current, power consumption, output voltage, and peak power. Additionally, the device features a black-box function that captures and stores telemetry data and device status in the event of a warning or fault. With its advanced features and capabilities, the LM5056APMHE/NOPB is a valuable tool for system management, providing important insights through the SMBus interface
