2 A Low-Voltage

PMOS-NMOS Bridge Driver

FAN3268-F085

Description

The FAN3268 dual 2 A gate driver is optimized to drive a high−side

P−channel MOSFET and a low−side N−channel MOSFET in motor

control applications operating from a voltage rail up to 18 V. The

driver has TTL 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 if the V

supply voltage is below the

operating level. Internal 100 kW resistors bias the non−inverting

output low and the inverting output to V to keep the external

MOSFETs off during startup intervals when logic control signals may

not be present.

CASE 751EB

MARKING DIAGRAM

The FAN3268 driver incorporates MillerDrivet 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 FAN3268 has two independent enable pins that default to on if

not connected. If the enable pin for non− inverting channel A is pulled

low, OUTA is forced low; if the 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.
