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 Semiconductors 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. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

V to SYS Path BUS Surge Protection under IEC 61000-4-5 Channel one (V to V ) is an active-low, 28 V/3.5 A BUS OUT rated, power MOSFET switch with an internal clamp V : 100 V BUS supporting 100 V surge protection, fixed OVP at 13.9 V Input Voltage Range (400 mV). Channel two (V to SYS) is a active-high, BUS 6 V/6 A rated, power MOSFET, fixed OVP at 5.25 V V : 2.7 V ~ 13.5 V BUS (250 mV) and Reverse Current Blocking (RCB) during Max. Continuous Current Capability its OFF State. V Path: 3.5 A OUT POK is paired with always ON LDO to power SYS Path: 6 A downstream devices when VBUS is greater than 2.7 V, regardless of OVLO, EN1 and EN2 State. This provides Ultra Low On-Resistance system power supply without battery. - V Path: Typ. 28 m OUT The FPF3488 is available in a 28-bump, 1.67 mm x - SYS Path: Typ. 33 m 2.96 mm Wafer-Level Chip-Scale Package (WL-CSP) with 0.4 mm pitch. Over-Voltage Protection (OVP) - V Path: 13.9 V 400 mV OUT Applications - SYS Path: 5.25 V 250 mV Mobile Handsets and Tablets Always ON LDO Output POK for V Detection BUS Wearable Devices and System Power Up without Battery Active LOW Control for V to V Path BUS OUT Active HIGH Control for V to SYS Path BUS Additional Information Active HIGH Control for Device Shutdown For the full datasheet, please contact a Fairchild CMOS output FLAG for VBUS to SYS Path Sales Representative.
