LM25066APSQE/NOPB

LM25066APSQE/NOPB Description Hot Swap Voltage Controllers System Pwr Mgmt & Protect IC w/ PMBus
The LM25066A combines a high-performance hotswap controller with a PMBus™ compliant SMBus/I2C interface to accurately measure, protect and control the electrical operating conditions of computing and storage blades connected to a backplane power bus.
The LM25066A continuously supplies real-time power, voltage, current, temperature and fault data to the system management host via the SMBus interface. LM25066APSQE/NOPB
