FAN3226 / FAN3227 / FAN3228 / FAN3229 Dual 2-A High-Speed, Low-Side Gate Drivers April 2013 FAN3226 / FAN3227 / FAN3228 / FAN3229 Dual 2-A High-Speed, Low-Side Gate Drivers Features Description Industry-Standard Pinouts The FAN3226-29 family of dual 2 A gate drivers is designed to drive N-channel enhancement-mode 4.5-V to 18-V Operating Range MOSFETs in low-side switching applications by 3-A Peak Sink/Source at V = 12 V DD providing high peak current pulses during the short 2.4 A-Sink / 1.6-A Source at V = 6 V OUT switching intervals. The driver is available with either TTL or CMOS input thresholds. Internal circuitry Choice of TTL or CMOS Input Thresholds provides an under-voltage lockout function by holding Four Versions of Dual Independent Drivers: the output low until the supply voltage is within the - Dual Inverting + Enable (FAN3226) operating range. In addition, the drivers feature matched internal propagation delays between A and B channels - Dual Non-Inverting + Enable (FAN3227) for applications requiring dual gate drives with critical - Dual Inputs in Two Pin-Out Configurations: timing, such as synchronous rectifiers. This enables connecting two drivers in parallel to effectively double o Compatible with FAN3225x (FAN3228) the current capability driving a single MOSFET. o Compatible with TPS2814D (FAN3229) The FAN322X drivers incorporate MillerDrive Internal Resistors Turn Driver Off If No Inputs architecture for the final output stage. This bipolar- MillerDrive Technology MOSFET combination provides high current during the Miller plateau stage of the MOSFET turn-on / turn-off 12-ns / 9-ns Typical Rise/Fall Times (1-nF Load) process to minimize switching loss, while providing rail- Under 20-ns Typical Propagation Delay Matched to-rail voltage swing and reverse current capability. within 1 ns to the Other Channel The FAN3226 offers two inverting drivers and the Double Current Capability by Paralleling Channels FAN3227 offers two non-inverting drivers. Each device 8-Lead 3x3 mm MLP or 8-Lead SOIC Package has dual independent enable pins that default to ON if not connected. In the FAN3228 and FAN3229, each Rated from 40C to +125C Ambient channel has dual inputs of opposite polarity, which Automotive Qualified to AEC-Q100 (F085 Version) allows configuration as non-inverting or inverting with an optional enable function using the second input. If one Applications or both inputs are left unconnected, internal resistors bias the inputs such that the output is pulled low to hold Switch-Mode Power Supplies the power MOSFET off.
