12V Hot-Plug Switch
General Description
The DS4560 is a self-contained hot-plug switch intend-
ed to be used on +12V power buses to limit through
current and to control the power-up output-voltage
ramp. The device contains an on-board 25mΩ n-chan-
nel power MOSFET that is actively closed-loop con-
trolled to ensure that an adjustable current limit is not
exceeded. The maximum allowable current through the
device is determined by an external resistor connected
to the ILIM pin.
The DS4560 also contains the ability to control the
power-up output-voltage ramp. A capacitor connected
to the VRAMP pin sets the desired voltage ramp rate.
The output voltage is unconditionally clamped to keep
input overvoltage stresses from harming the load. The
DS4560 also contains an adjustable power-up timer. A
capacitor connected to the TIMER pin determines how
long after power-on reset the DS4560 should wait
before starting to apply power to the load. The TIMER
pin can also be driven with a digital logic output to cre-
ate a device-enable function.
The DS4560 contains an on-board temperature sensor
with hysteresis. If operating conditions cause the
device to exceed an internal thermal limit, the DS4560
either unconditionally shuts down and latches off await-
ing a power-on reset (DS4560S-LO), or it waits until the
device has cooled by the hysteresis amount and then
restarts (DS4560S-AR).
