Description
The FAN3111 1A gate driver is designed to drive an Nchannel enhancement-mode MOSFET in low-side switching applications.
Two input options are offered: FAN3111C has dual CMOS inputs with thresholds referenced to VDD for use with PWM controllers and other input-signal sources that operate from the same supply voltage as the driver.
FEATUREs
◾ 1.4A Peak Sink / Source at VDD = 12V
◾ 1.1A Sink / 0.9A Source at VOUT = 6V
◾ 4.5 to 18V Operating Range
◾ FAN3111C Compatible with FAN3100C Footprint
◾ Two Input Configurations:
◾ Dual CMOS Inputs Allow Configuration as
Non-Inverting or Inverting with Enable Function
◾ Single Non-Inverting, Low-Voltage Input for
Compatibility with Low-Voltage Controllers
◾ Small Footprint Facilitates Distributed Drivers for
Parallel Power Devices
◾ 15ns Typical Delay Times
◾ 9ns Typical Rise / 8ns Typical Fall times with 470pF
Load
◾ 5-Pin SOT23 Package
◾ Rated from –40°C to 125°C Ambient
APPLICATIONs
◾ Switch-Mode Power Supplies
◾ Synchronous Rectifier Circuits
◾ Pulse Transformer Driver
◾ Logic to Power Buffer
