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.

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.
Switch output. The load being driven by the switch is connected to this pin.
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.

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.
