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.

• TTL and CMOS Input Compatibility

• Thermal Shutdown Protection

• 300kHz Operation

• Low-Cost TO-220 Package
