Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor's system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers.

FPF3042 IntelliMAXTM 18 V-Rated, Dual-Input, Single-Output, Power-Source-Selector Switch Features Description The FPF3042 is an 18 V-rated Dual-Input Single-Output (DISO) load switch consisting of two channels of slewrate-controlled, low-on-resistance, N-channel MOSFET switches with protection features. The slew-ratecontrolled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on the input power rails. The input voltage range operates from 4.0 V to 12.4 V at both VBUS and VIN to align with the needs of high-voltage portable device power rails. Dual-Input, Single-Output Load Switch (DISO) Input Supply Operating Range: - 4.0 V~12.4 V at VIN - 4.0 V~12.4 V at VBUS Typical RON: 95 m at VIN=5 V 70 m at VBUS=5 V Both VIN and VBUS have the over-voltage protection of 14 V (typical) to avoid damage to the system. Bidirectional Switch for VIN and VBUS Slew Rate Controlled: - VIN and VBUS bidirectional switching allows reverse current from VOUT to VIN or VBUS for On-The-Go, (OTG) Mode. The switching is controlled by logic input EN and VIN_SEL is capable of interfacing directly with low-voltage control signal General-Purpose Input / Output (GPIO). 50 s at VIN for < 4.7 F COUT 90 s at VBUS for < 4.7 F COUT Maximum ISW: 2.7 A per Channel Break-Before-Make Transition FPF3042 is available in 1.76 mm x 1.96 mm WaferLevel Chip-Scale Package (WLCSP), 16-bump, 0.4 mm pitch.

FPF3042 * Rev. 1.0.1 Input Output Description Enable: Active HIGH; EN voltage 2.5 V can power internal circuit when VIN and VBUS are absent. 1 M pull-down resistor is included. Supply Selector & Status: Input power source selection input and status output. This signal is ignored during EN=LOW. Selector input during EN=HIGH: HIGH = switch VIN to VOUT / LOW = switch VBUS to VOUT. Status output during EN=LOW: HIGH = VIN is used for VOUT / LOW = VBUS is used for VOUT. Default Supply Selector during EN=LOW: Floating = VBUS connects to VOUT. LOW = VIN connects to VOUT. This signal is ignored during EN=HIGH. 1 A pull-up current source is included. Other Supply Input Status: Open-drain output. HIGH-Z = both VIN and VBUS are valid. LOW = the other power source is not valid.

Even if both VIN and VBUS are unavailable, reverse power can be supported if internal control circuitry is powered by EN. When EN is LOW, the input source is selected by DF_IN and the number of valid input sources. If only one input source is valid (greater than VUVLO(MAX)), the source is selected automatically, regardless of DF_IN, to make charging path in case the battery is depleted. If both VBUS and VIN have valid input sources, the input source is selected by DF_IN. If DF_IN is LOW, VIN is selected. If DF_IN is HIGH or floating, VBUS is selected. DF_IN is biased HIGH with an internal 1 A pull-up current source. Table 3. FPF3042 supports reverse-current blocking during EN LOW and an unselected channel. Thermal Shutdown During thermal shutdown, the power switch is turned off if junction temperature exceeds 150C to avoid damage.

The system can recognize an input power source change between 5 V TA and 5 V WC without detection circuitry because FPF3042 has a 100 ms transition delay. OTG Mode can be supported without an additional power path, such as a MOSFET. VBUS LOW VIN LOW NO NO X X Floating VIN_SEL can be the status output to indicate which input power source is used during EN is LOW. If VIN is used, VIN_SEL shows HIGH. If VBUS is used, VIN_SEL shows LOW. The voltage level of HIGH signal is 5.3 V if any one of VIN, VBUS, or EN is higher than 5.3 V.
