Connection to lower emitters of output stage for insertion of
current sense resistor
Input connected to the comparators. The voltage across the
sense resistor is feedback to this input throught the low pass
filter RC CC. The higher power transistors are disabled
when the sense voltage exceeds the reference voltage of
the selected comparator. When this occurs the current
decays for a time set by R

Output Connection. The output stage is a H bridge formed
by four transistors and four diodes suitable for switching
applications
Ground connection, they also conducts heat from die to
printed circuit copper
See input 1 (pins 9, 17)
These pins and pins 8, 20 (input 0) are logic inputs which
select the outputs of the comparators to set the current
level. Current also depends on the sensing resistor and
reference voltage. See functional description
