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.

The gate driver is rated to 2.8-A peak current 1% at 25C, 2.5% Total Variation at V of 12 V and is designed to drive an N-channel DD Gate Driver enhancement-mode MOSFET in low-side switching Peak 2.8-A Sink / 2.5-A Source at V = 12 V DD applications. The FAN3180 also integrates a 3.3-V, 15- mA LDO with tight voltage tolerance of 1% at 25C and Controlled Output Pulses at Startup and Shutdown 2.5% of total variation for powering external Non-Inverting Logic Configuration microcontrollers. TTL-Compatible Input Thresholds Internal circuitry provides an Under-Voltage Lockout 23-ns Typical Delay Time (UVLO) function by holding the output low until the 19-ns / 13-ns Rise and Fall Times with 1-nF Load supply voltage is within the operating range and the first full input pulse is detected. The FAN3180 has UVLO General thresholds of 4.75-V V and 4.55-V V and a ON OFF -40C to +125C Operation Temperature maximum standby supply current of 200 A. 5-V to 18-V Operating Range The driver delivers fast MOSFET switching performance V / V UVLO of 4.75 V / 4.55 V ON OFF to maximize efficiency in high-frequency power 200-A Maximum Standby Supply Current converter designs. It incorporates the MillerDrive architecture for the final output driver stage. This Lead (Pb)-Free Green 5-Pin SOT23 Package bipolar-MOSFET combination provides high peak current during the Miller plateau stage of the MOSFET Applications turn-on / turn-off process to minimize switching loss, while providing rail-to-rail voltage swing and reverse- Gate Drive with Power for the MCU current capability.
