Beschreibung

Demonstration circuit 2024A features the LTC®4282 highcurrent Hot Swap™ controller. The LTC4282 is well suitedto high power applications because the precise monitoringcapability and accurate current limiting reduces theextremes in which both loads and power supplies mustsafely operate. Non-volatile configuration allows for flexibilityin the autonomous generation of alerts and responseto faults. The LTC4282 provides a rich set of features tosupport Hot Swap applications including:nn 12-/16-Bit ADC Monitors Current, Voltage, Power andEnergynn Controls Two Sets of Parallel MOSFETs for High CurrentApplicationsnn I2C/SMBus InterfaceL, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and HotSwap is a trademark of Linear Technology Corporation. All other trademarks are the property oftheir respective owners.nn Non-Volatile Configuration and Logging Functionsnn Generates Alerts on ADC Measurements Outside Limitsnn Software Adjustable Current Limit with Foldbacknn Three General Purpose Input/OutputsAvailable in a 32-pin 5mm × 5mm QFN package, theLTC4282 is showcased on DC2024A configured for a12V/100A application. By changing a few passive components,2.9V to 30V applications can easily be evaluated.
