Latchoff Version (DS4560S-LO)

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 to be enabled.

Overvoltage Limit

The overvoltage-limiting clamp monitors the VRAMP

level compared to an internal voltage reference. When

age of the n-channel power MOSFET is reduced, limit-

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.

Applications Information

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.
