Descriptions
These
differentiation of a pin from electrical signals and
components connected to that pin. For example, VOUT
is the switch’s output pin, while V
signal output voltage present at the VOUT pin.

Switch output. The load being driven by the switch is connected to this pin.
Description
Supply input. This pin provides power to both the output switch and the switch’s internal
control circuitry.
Ground.
Switch Enable (Input):
Fault status. A logic LOW on this pin indicates the switch is in current limiting, or has been
shut down by the thermal protection circuit. This is an open-drain output allowing logical
OR’ing of multiple switches.
Slew rate control. Adding a small value capacitor between this pin and VIN slows turn-ON of
the power FET.
Variable Under Voltage Lockout (VUVLO): Monitors the input voltage through a resistor
divider between VIN and GND. Shuts the switch off if voltage falls below the threshold set by
the resistor divider. Previously called VUVLO.
Set current limit threshold via a resistor connected from ILIMIT to GND.
On MLF packages connect EP to GND.
OUT
Description
Electrical signal input voltage present at the VIN pin.
Ground.
Electrical signal input voltage present at the ENABLE pin.
Electrical signal output voltage present at the FAULT/ pin.
Capacitance value connected to the CSLEW pin.
Electrical signal output voltage present at the VOUT pin.
VUVLO internal reference threshold voltage. This voltage is compared to the VUVLO pin
input voltage to determine if the switch should be disabled. Reference threshold voltage
has a typical value of 250mV.
Capacitance value connected in parallel with the load. Load capacitance.
Electrical signal output current present at the VOUT pin.
Switch’s current limit. Fixed at factory or user adjustable.
