FAN3223 / FAN3224 / FAN3225 is a 4A high-performance low-side gate driver produced by Fairchild Semiconductor Corporation, with industry-standard pinouts, operating voltage range of 4.5 to 18V, peak sink/source current of 5A (VDD=12V), sink current of 4.3A (VOUT=6V), TTL or CMOS input threshold selection, three versions of dual independent drivers: dual inverting + enable (FAN3223), dual non-inverting + enable (FAN3224) and dual-inputs (FAN3225), internal resistors turn the driver off if no inputs, using MillerDrive™ technology, typical rise/fall time is 12ns/9ns (2.2nF load), typical propagation delay is less than 20ns, matched within 1ns to the other channel, and double current capability by paralleling channels, using 8-lead 3x3mm MLP or 8-lead SOIC package, rated from -40°C to +125°C ambient temperature.
The FAN3223, FAN3224, and FAN3225 family of dual 4A gate drivers is designed to drive N-channel enhancement-mode MOSFETs in low-side switching applications. These drivers provide high peak current pulses during short switching intervals and feature an under-voltage lockout function to hold the output LOW until the supply voltage is within the operating range. The family offers a choice of TTL or CMOS input thresholds and includes internal circuitry to match propagation delays between channels.
