3946
Half-Bridge Power MOSFET Controller
The A3946 is designed speci
fi
cally for ap pli ca ions that require
high power unidirectional dc motors, three-phase brushless dc motors, or
other inductive loads. The A3946 provides two high-current gate drive
outputs that are capable of driving a wide range of power N-channel
MOSFET
s. The high-side gate driver switches an N-channel
MOSFET
that controls current to the load, while the low-side gate driver switches
an N-channel
MOSFET
as a synchronous recti
fi
er.
A bootstrap capacitor provides the above-battery supply voltage
required for N-channel MOSFETs. An internal charge pump for the
high side allows for dc (100% duty cycle) operation of the half-bridge.
The A3946 is available in a choice of two power pack ag es: a
16-lead
SOIC
with copper batwing power tab (part number suf
fi
x
LB
),
and a 16-lead
TSSOP
with ex posed thermal pad (suf

).
