Linear Technology DC2024A Demo Manual

Description
Demonstration circuit 2024A features the
current Hot Swap controller. The LTC4282 is well suited
to high power applications because the precise monitor-
ing capability and accurate current limiting reduces the
extremes in which both loads and power supplies must
safely operate. Non-volatile configuration allows for flex-
ibility 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-/16-Bit ADC Monitors Current, Voltage, Power and

Available in a 32-pin 5mm × 5mm QFN package, the
LTC4282 is showcased on DC2024A configured for a
12V/100A application. The DC2024A-B has an included
programming socket to allow programming an LTC4282
for prototyping purposes prior to its permanent installation
on a PCB. The DC2024A-A does not have this socket. By
changing a few passive components, 2.9V to 30V applica-
tions can easily be evaluated.
