Pin N° Pin name Function
14 DIAG1
DIAGNOSTIC 1 output. This open drain reports the IC working
conditions. (See diagnostic truth Table 7)
15 DIAG2
DIAGNOSTIC 2 output. This open drain reports the IC working
conditions. (See diagnostic truth Table 7)
18 IN- Comparator non inverting input
17 IN+ Comparator inverting input
19 OUTSTATUS
This current source output is capable of driving a LED to signal the
status of the output pin. The pin is active (source current) when the
output pin is considered high (See Figure 3)
