2A Low-Voltage,
PMOS-NMOS Bridge Driver

Favorite

Overview

The FAN3268 dual 2 A gate driver is optimized to drive a high-side P-channel MOSFET and a low-side Nchannel MOSFET in motor control applications operating from a voltage rail up to 18 V. The driver hasTTL input thresholds and provides buffer and level translation functions from logic inputs. Internal circuitry provides an under-voltage lockout function that prevents the output switching devices from operating ifthe VDD supply voltage is below the operating level.Internal 100 kΩ resistors bias the non-inverting output low and the inverting output to VDD to keep the external MOSFETs off during startup intervals when logic control signals may not be present.The FAN3268 driver incorporates 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-offprocess to minimize switching loss, while providing railto-rail voltage swing and reverse current capability.The FAN3268 has two independent enable pins that default to on if not connected. If the enable pin for noninverting channel A is pulled low, OUTA is forced low; ifthe enable pin for inverting channel B is pulled low, OUTB is forced high. If an input is left unconnected, internal resistors bias the inputs such that the external MOSFETs are off.
