DataSheeT enpirion power solutions ET6160LI 70A Power Stage Power Stage with Integrated Current and Temperature Sense DESCRIPTION FEATURES The Intel Enpirion ET6160LI is a monolithic Smart Up to 70A of Current Capability Power Stage with integrated current and temperature High Efficiency for FPGA and ASIC Core Supplies monitors. The power stage is optimized to operate Wide Input Range 4.5V 16V with the ED8401 scalable multi-phase controller. Integrated High Accuracy Current Monitor (IMON) The ET6160LI monolithic output stage offers high True Junction Temperature Monitor (TMON) system efficiency while offering high switching Catastrophic Fault Protection frequencies from 500kHz to 1MHz. Monolithic construction provides excellent thermal impedance Over Temperature Protection (OTP) for HS, LS, and Driver sections and does not require High/Low-Side Current Protection (OCP) complex internal copper clip technology. Under Voltage Lock-Out (UVLO) The integration of the drivers and the MOSFETs Over Voltage Lock-Out (OVLO) allows for very accurate current reconstruction Optimized for Operation with ED840X Controllers (IMON) protecting against large transient events at Compact 5.0mm x 6.0mm x 0.7mm LGA Package the load. Integrated thermal information from the High Reliability Universal Footprint ET6160LI also helps the controller monitor the system health and react to temperature driven RoHS Compliant, MSL Level 3, 260C Reflow events. APPLICATIONS The 5x6mm package is designed specifically for high FPGA and ASIC Core Power Rails thermal stress environments. The pad layout is 5G Wireless Base Station and Remote Radio designed to reduce internal and solder joint stress High Reliability Communications Infrastructure from temperature cycling thereby increasing long term reliability of the package and solder joints.
