The is a TTL input dual non- inverting output Low-Side Gate Driver designed to drive N-channel enhancement-mode MOSFETs in low-side switching applications by providing high peak current pulses during the short switching intervals. 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 driver features 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 MOSFET. This bipolar-MOSFET combination provides high current during the Miller plateau stage of the MOSFET turn-OB/turn-OFF process to minimize switching loss, while providing rail-to-rail voltage swing and reverse current capability.
