DS4560S-AR+ (MAXIM INTEGRATED PRODUCTS)

The DS4560S-AR+ is a 12V hot plug switch in 8 pin NSOIC package. The DS4560 is a self-contained hot-plug switch intended 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 25mohm n-channel power MOSFET that is actively closed-loop controlled 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. It also contains an adjustable power-up timer and an on-board temperature sensor with hysteresis. If operating conditions cause the device to exceed an internal thermal limit, the DS4560 waits until the device has cooled by the hysteresis amount and then restarts.
