(v in = 1v, v on = 3v) n-channel mosfet and is customized for a low-input operating range of 0.8v to 1.8v. the on pin controls the state of the switch. the fpf1014 contains a 60 ? (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 vo ltage should exceed the input voltage by 2v. this device is compatible with a gpio (general-purpose input / out put) port, where the logic voltage level can be configured to 4v v on v in + 2v and power consumed is less than 1 a in steady state. figure 20. timing diagram where: td on = delay on time t r = v out rise time t on = turn-on time td off = delay off time t f = v out fall time t off = turn-off time figure 21. typical application
