LM5066IPMHX/NOPB Hot Swap Controller | 10-80V | PMBus Interface | 28-HTSSOP Package | Texas Instruments

The LM5066IPMHX/NOPB is a high-performance hot swap controller from Texas Instruments (TI), designed to provide robust circuit protection and precise real-time monitoring for 10V to 80V systems. The device integrates an I2C/SMBus interface compliant with PMBus and Node Manager 2.0/3.0 standards, delivering real-time voltage, current, power, temperature, and fault data to the system management host. Its precision telemetry accuracy reaches V (±1.25%), I (±1.75%), and P (±2.5%), and it supports energy monitoring via the Read_EIN command. The device features programmable UV/OV/ILIMIT thresholds, programmable FET SOA protection, a programmable fault timer (tFAULT), and fast short-circuit protection, along with external FET temperature sensing and failed FET detection. Housed in a 28-PowerTSSOP package (9.7×4.4mm), it operates from -40°C to +125°C, making it ideal for 48V servers, base station power distribution, networking routers and switches, and PLC power management. We supply 100% original products with fast delivery and professional technical support.
