7 www.fairchildsemi.com FPF1013/4 rev. b1 FPF1013/4 intellimax tm 1v rated advanced load management products description of operation the FPF1013/4 are low r ds(on) n-channel load switches with controlled turn-on. the core of each device is a 17m ? (v in = 1v, v on = 3v) n-channel mosfet and is customized for a low input operating range of 0.8 to 1.8v. the on pin controls the state of the switch. the fpf1014 contains a 60 ? (typ) on-chip resistor which is connected internally from v out to gnd for quick output discharge when the switch is turned off. on/off control the on pin is active high and it controls the state of the switch. applying a continuous high signal will hold the switch in the on state. in order to minimize the switch on resistance, the on pin voltage should exceed the input voltage by 2v. this device is compatible with a gpio (gener al purpose input/output) port, where the logic voltage level can be configured to 4v v on v in +2v and power consumed is less than 1a in steady state. 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 v on v out 10% 10% 10% 90% 90% 90% td on t r t on td off t f t off application information typical application input capacitor to limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns-on, a capacitor must be placed between v in and gnd. for minimized voltage drop, especially when the operating voltage approaches 1v a 10f ceramic capacitor should be placed close to the v in pins. higher values of c in can be used to further reduce the voltage drop during higher current modes of operation. output capacitor a 0.1f capacitor, c l , should be placed between v out and gnd. this capacitor will prev ent parasitic board inductance from forcing v out below gnd when the switch turns-off. if the application has a capacitive load, the fpf1014 can be used to discharged that load through an on-chip output discharge path. board layout for best performance, all traces should be as short as possible. to be most effective, the input and output capacitors should be placed close to the device to mini mize the effects that parasitic trace inductances may have on normal and short-circuit operation. using wide traces or large copper planes for all pins (v in , v out , on and gnd) will help minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance. off on on v in gnd FPF1013/4 v out v in = 0.8-1.8v c in r l c l
8 www.fairchildsemi.com FPF1013/4 rev. b1 FPF1013/4 intellimax tm 1v rated advanced load management products improving thermal performance an improper layout could result in higher junction temperature. this concern applies when cont inuous operation current is set to maximum allowed current and switch turns into a large capacitive load that introduc e high inrush current in the transient. since FPF1013/4 does not have thermal shutdown feature a proper layout can ess entially reduce power dissipation of the switch in transient and prevents switch to exceed the maximum absolute power dissipation of 1.2w. the v in , v out and gnd pins will dissipate most of the heat generated during a high load current condition. the layout suggested in figure 16 provides each pin with adequate copper so that heat may be transferred as efficiently as possible out of the device. the on pin trace may be laid-out diagonally from the device to maximize the area available to the ground pad. placing the input and output capaci tors as close to the device as possible also contributes to heat dissipation, particularly during high load currents. figure 16: proper layout of output, input and ground copper area demo board layout FPF1013/4 demo board has the components and circuitry to demonstrate FPF1013/4 load swit ches functions. thermal performance of the board is improved using a few techniques recommended in the layout recommendations section of datasheet. figure 17.
