Operational Description
The FPF1013/4 are low-RDS(ON) N-channel load switches
with controlled turn-on. The core of each device is a
17 mΩ (VIN = 1 V, VON = 3 V) N-channel MOSFET and is
customized for a low-input operating range of 0.8 V to
1.8 V. The ON pin controls the state of the switch.
The FPF1014 contains a 60 Ω (typical) on-chip resistor,
which is connected internally from VOUT to GND for
quick output discharge when the switch is turned off.
On / Off Control
The ON pin is active HIGH and controls the state of the
switch. Applying a continuous HIGH signal holds the
switch in the ON state. To minimize the switch on
resistance, the ON pin voltage should exceed the input
voltage by 2 V. This device is compatible with a GPIO
(General-Purpose Input / Output) port, where the logic
voltage level can be configured to 4 V ≥ VON ≥ VIN + 2 V
and power consumed is less than 1 μA in steady state.
