Description
The FPF2193, FPF2194, and FPF2195 form a series of
load switches that provides full protection to systems
and loads that may encounter large current conditions.
These devices contain a 55 mcurrent-limited P-
channel MOSFET that can operate over an input
voltage range of 1.8 to 5.5 V. Internally, current is
prevented from flowing when the MOSFET is off and the
output voltage is higher than the input voltage. Switch
control is by a logic input (ON) capable of interfacing
directly with low-voltage control signals. Each part
contains thermal shutdown protection that shuts off the
switch to prevent damage to the part when a continuous
over-current condition causes excessive heating.
When the switch current reaches the current limit, the
parts operate in a constant-current mode to prohibit
excessive currents from causing damage. For the
FPF2193 and FPF2194, if the constant current condition
still persists after 30 ms, the parts shut off the switch
and pull the fault signal pin (FLAGB) LOW. The
FPF2193 has an auto-restart feature that turns the
switch on again after 450 ms if the ON pin is still active.
The FPF2194 does not have this auto-restart feature, so
the switch remains off until the ON pin is cycled. The
FPF2195 does not turn off after a current limit fault, but
remains in the constant-current mode indefinitely. The
minimum current limit can be set as low as 45 mA.
These parts are available in a space-saving six ball
advanced 0.98 x 1.48 mm WLCSP package.

Description
Current Limit Set Input. A resistor from ISET to ground sets the current limit for the switch.
Supply Input. Input to the power switch and the supply voltage for the IC.
Switch Output. Output of the power switch.
Fault Output. Active LOW, open-drain output that indicates an over-current supply, under-
voltage, or over-temperature state.
Ground.
ON control input, active HIGH.
