Product Details

Demonstration circuit 2442A features the LTC4282 high current Hot Swap controller. The LTC4282 is well suited to high power applications because the precise monitoring capability and accurate current limiting reduces the extremes in which both loads and power supplies must safely operate. Nonvolatile configuration allows for flexibility in the autonomous generation of alerts and response to faults. The LTC4282 provides a rich set of features to support Hot Swap applications including:

12- to 16-Bit ADC Monitors Current, Voltage, Power and Energy
Controls Two Sets of Parallel MOSFETs for High Current Applications
I²C/SMBus Interface
Nonvolatile Configuration and Logging Functions
Generates Alerts on ADC Measurements Outside Limits
Software Adjustable Current Limit with Foldback
Three General Purpose Input/Outputs
