UC2950,pdf(Half-Bridge Bipolar

This device is a monolithic integrated circuit designed to provide high-current switching with low saturaTIon voltages when acTIvated by low-level logic signals. Source and sink switches may be independently acTIvated without regard to TIming as a built-in interlock will keep the sink off if the source is on.

This driver has the high current capability to drive large capacitive loads with fast rise and fall times; but with high-speed internal flyback diodes, it is also ideal for inductive loads. Two UC2950s can be used together to form a full bridge, bipolar motor driver compatible with high frequency chopper current control.
