DEMO MANUAL DC1051A
LTC4217
2A Integrated
Hot Swap Controller
Description
Demonstration circuit 1051A includes two separate circuits
for performance evaluation of the LTC
®
4217 2A integrated
Hot Swap™ controller. This integrated circuit includes
a power MOSFET to save board area and to minimize
external component count. The standard version of the
controller (LTC4217) is intended to operate with 2.9V to
26.5V rails, while the LTC4217-12 has internal adjustment
for 12V applications.
The circuit of DC1051A located on the upper board area
is assembled with the LTC4217 configured for operation
with a 24V rail. The lower circuit includes the LTC4217-12.
Current limit features of both circuits are identical, with
5% accuracy and a distinctive foldback property.
The LTC4217 features a ground-referred current monitor.
The current monitor sources a current that is proportional
to the sense voltage and it may be converted to a voltage
signal with an appropriate resistor.
The current limit may be reduced by placing an external
resistor between GND and the ISET pin.
The DC1051A schematic allows the LTC4217 to operate in
turn-on and turn-off modes as well as in the steady-state
mode with different loads, and in the fault mode.
The LTC4217 features an overtemperature protection
circuit, and protects the load from overvoltage and un-
dervoltage conditions.
