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.

Surge Protection under IEC 61000-4-5 Channel one (V to V ) is an active-low, 28 V/3.5 A BUS OUT V : 100 V BUS rated, power MOSFET switch with an internal clamp Input Voltage Range supporting 100 V surge protection, fixed OVP at 5.8V when OVSEL is tied to GND or 13.9V (FPF34891) / V : 2.7 V ~ 13.5 V BUS 10.4V (FPF34892) when OVSEL is floating. Max. Continuous Current Capability Channel two (V to BAT) is an active-high, 5 V/6 A BUS V Path: 3.5 A OUT rated, power MOSFET, fixed OVP at VBUS is 5.8 V BAT Path: 6 A (200 mV) and Reverse Current Blocking (RCB) during Ultra Low On-Resistance its OFF State. OVLO at BAT can be programmed by external resistors. The Over-Voltage status will be - V Path: Typ. 28 m OUT latched and FLAG will signal the fault by pulling low. To - BAT Path: Typ. 33 m re-start this channel from OVLO, EN2 need to be toggled from LOW to HIGH.
