Half-Bridge Bipolar Switch  
FEATURES  
DESCRIPTION  
Source or Sink 4.0A  
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 acti-  
vated without regard to timing as a built-in interlock will keep the sink off if  
the source is on.  
Supply Voltage to 35V  
High-Current Output Diodes  
Tri-State Operation  
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 cur-  
rent control.
