3946  
Half-Bridge Power MOSFET Controller  
The A3946 is designed specically for applications 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  
MOSFETs. The high-side gate driver switches an N-channel MOSFET

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 packages: a  
16-lead SOIC with internally fused leads (part number sufx LB), and  
a 16-lead TSSOP with exposed thermal pad (sufx LP). Both packages  
have a lead (Pb) free version, with 100% matte tin plated leadframes  
(sufx -T).
