LTC4282
Analog DevicesLTC4282 is an Analog Devices high-current hot swap controller with I2C monitoring — for datacenter backplanes and server blades requiring safe live insertion: 2.9 V to 33 V operation, 12 V gate drive for low-RDS(ON) MOSFETs, programmable current limit with 2% accuracy, and MOSFET power limiting with foldback. The 12-/16-bit ADC reports current, voltage, power and energy over I2C/SMBus, while internal EEPROM stores configuration — the telemetry datacenter operators need for per-slot power accounting. Controls two parallel MOSFETs for SOA sharing in high-current designs. Selection advice: the I2C interface coexists with PMBus devices on the same bus, simplifying backplane management architecture; for dual-channel needs consider the LTC4222. ADI lists this as recommended for new designs. Parameters verified against Analog Devices documentation.
