FPF1320 / FPF1321 IntelliMAX™ Dual-Input Single-Output Advanced Power Switch with True Reverse-Current Blocking Features Description DISO Load Switches The FPF1320/21 is a Dual-Input Single-Output (DISO) load switch consisting of two sets of slew-rate controlled, low on-resistance, P-channel MOSFET switches and integrated analog features. The slew-ratecontrolled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on the power rails. The input voltage range operates from 1.5V to 5.5V to align with the requirements of low-voltage portable device power rails. FPF1320/21 performs seamless power-source transitions between two input power rails using the SEL pin with advanced breakbefore-make operation.

The core is a 50mΩ P-channel MOSFET and controller capable of functioning over a wide input operating range of 1.5V to 5.5V per channel. The EN and SEL pins are activeHIGH, GPIO/CMOS-compatible input. They control the state of the switch and input power source selection, respectively. TRCB functionality blocks unwanted reverse current during both ON and OFF states when higher VOUT than VINA or VINB is applied. FPF1321 has a 65Ω output discharge path during off. Power Source Selection Input Capacitor FPF1320/1 adopts an advanced break-before-make control, which can result in minimized output voltage drop during the transition time. Input power source selection can be controlled by the SEL pin. When SEL is LOW, output is powered from VINA while SEL is HIGH, VINB is powering output. The SEL signal is ignored during device OFF. Output Voltage Drop during Transition Output voltage drop usually occurs during input power source transition period from low voltage to high voltage. The drop is highly dependent on output capacitance and load current. To limit the voltage drop on the input supply caused by transient inrush current when the switch turns on into a discharged load capacitor; a capacitor must be placed between the VINA or VINB pins to the GND pin. At least 1µF ceramic capacitor, CIN, placed close to the pins, is usually sufficient. Higher-value CIN can be used to reduce more the voltage drop. Output Capacitor Capacitor COUT of at least 1µF is highly recommended between the VOUT and GND pins to achieve minimized output voltage drop during input power source transition. This capacitor also prevents parasitic board inductance. Inrush Current True Reverse-Current Blocking Inrush current occurs when the device is turned on. Inrush current is dependent on output capacitance and slew rate control capability, as expressed by: The true reverse-current blocking feature protects the input source against current flow from output to input regardless of whether the load switch is on or off. I INRUSH COUT VIN VINITIAL I LOAD tR Board Layout (1) 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 minimize the effect that parasitic trace inductance on normal and short-circuit operation. Wide traces or large copper planes for power pins (VINA, VINB, VOUT and GND) minimize the parasitic electrical effects and the thermal impedance. where: COUT: Output capacitance; tR: Slew rate or rise time at VOUT; VIN: Input voltage, VINA or VINB; VINITIAL: Initial voltage at COUT, usually GND; and ILOAD: Load current. Higher inrush current causes higher input voltage drop, depending on the distributed input resistance and input capacitance. High inrush current can cause problems.
