• Manufacturer Part Number: ds4560
• Description: 12v Hot-plug Switch
• Manufacturer: Maxim Integrated Products, Inc.

Once the latchoff version has entered thermal shut-
down, it does not attempt to turn back on. The only way
to turn this device back on is to cycle the power to the
device. When power is reapplied to V
temperature needs to be less than T
device to be enabled.
The overvoltage-limiting clamp monitors the VRAMP
level compared to an internal voltage reference. When
the voltage on VRAMP exceeds V
age of the n-channel power MOSFET is reduced, limit-
ing the voltage on LOAD to V
increases. If the device is in overvoltage for an extend-
ed period of time, the device may overheat and enter
thermal shutdown. This is caused by the power created
by the voltage drop across the power MOSFET and the
load current. See the THERMAL SHUTDOWN WITH
AUTORETRY graph for details.

The GND pin of the DS4560 is also a heat sink for the
device. This pin should be connected to a large trace
or plane capable of dissipating heat from the device.
