Descrição do produto
The FAN3223-25 family of dual 4A gate drivers is designed to drive N-channel enhancement-mode MOSFETs in low-side switching applications by providing high peak current pulses during the short switching intervals. The driver is available with either TTL or CMOS input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output LOW until the supply voltage is within the operating range. In addition, the drivers feature matched internal propagation delays between A and B channels for applications requiring dual gate drives with critical timing, such as synchronous rectifiers. This also enables connecting two drivers in parallel to effectively double the current capability driving a single MOSFETS. The FAN322X drivers incorporate MillerDrive? architecture for the final output stage. This bipolar-MOSFET combination provides high current during the Miller plateau stage of the MOSFET turn-on / turn-off process to minimize switching loss, while providing rail-to-rail voltage swing and reverse current capability. The FAN3223 offers two inverting drivers and the FAN3224 offers two non-inverting drivers. Each device has dual independent enable pins that default to ON if not connected. In the FAN3225, each channel has dual inputs of opposite polarity, which allows configuration as non-inverting or inverting with an optional enable function using the second input. If one or both inputs are left unconnected, internal resistors bias the inputs such that the output is pulled LOW to hold the power MOSFET OFF.

1. Estimates derived from thermal simulation; actual values depend on the application. 2. Theta_JL (QJL): Thermal resistance between the semiconductor junction and the bottom surface of all the leads (including any thermal pad)
that are typically soldered to a PCB. 3. Theta_JT (QJT): Thermal resistance between the semiconductor junction and the top surface of the package, assuming it is held at a uniform
temperature by a top-side heatsink. 4. Theta_JA (QJA): Thermal resistance between junction and ambient, dependent on the PCB design, heat sinking, and airflow. The value given
is for natural convection with no heatsink using a 2S2P board, as specified in JEDEC standards JESD51-2, JESD51-5, and JESD51-7, as appropriate. 5. Psi_JB (YJB): Thermal characterization parameter providing correlation between semiconductor junction temperature and an application circuit board reference point for the thermal environment defined in Note 4. For the MLP-8 package, the board reference is defined as the PCB copper connected to the thermal pad and protruding from either end of the package. For the SOIC-8 package, the board reference is defined as the PCB copper adjacent to pin 6. Psi_JT (YJT): Thermal characterization parameter providing correlation between the semiconductor junction temperature and the center of the top of the package for the thermal environment defined in Note 4.

About Utsource, if you want guaranteed good parts. They have a huge selection and they both accept small orders. Data sheets are online for everything they’ve got. If you open an account (free) you can check your order status and order history and re-order off past orders. The cheapest shipping option for both of them isPostal Service.
