onsemi FAN3122 High-Speed Low-Side Gate Driver

onsemi FAN3122 High-Speed Low-Side Gate Driver is a MOSFET driver that is designed to drive N-channel enhancement MOSFETs in low-side switching applications by providing high peak current pulses. The driver is available with a TTL input thresholds. Internal circuitry provides an under-voltage lockout function by holding the output low until the supply voltage is within the operating range. This onsemi driver incorporates the MillerDrive™ architecture for the final output stage. This bipolar / MOSFET combination provides the highest peak current during the Miller plateau stage of the MOSFET turn-on / turn-off process.
