DESCRIPTION
This device is a monolithic integrated circuit designed to provide high-cur-
rent 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.
