Features - 1.4 A Peak Sink / Source at VDD = 12 V - 1.1 A Sink / 0.9 A Source at VOUT = 6 V - 4.5 to 18 V Operating Range - FAN3111C patible 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 patibility with Low-Voltage Controllers - Small Footprint Facilitates Distributed Drivers for Parallel Power Devices - 15 ns Typical Delay Times - 9 ns Typical Rise / 8 ns Typical Fall times with 470 p F Load - 5-Pin SOT23 Package - Rated from - 40°C to 125°C Ambient 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. For use with low-voltage controllers and other inputsignal sources that operate from a lower supply voltage than the driver, that supply voltage may also be used as the reference for the input thresholds of the FAN3111E. This driver has a single, non-inverting, low-voltage input plus a DC input VXREF for an external reference voltage in the range 2 to 5 V. The FAN3111 is available in a lead-free finish industrystandard 5-pin SOT23.
