THERMAL PROTECTION
DESCRIPTION
The L292 is a monolithic LSI circuit in 15-lead
Multiwatt ® package. It is intended for use, together
with L290 and L291, as a complete 3-chip motor
positioning system for applications such as car-
riage/daisy-wheel position control in type-writes.
The L290/1/2 system can be directly controlled by
a microprocessor.
