Figure 27: A low resistance function switch
used.
Figure 28: If the resistance in the switch is not
guaranteed to be low enough, a safer design
can be used.
A.2.4 Reset
The
RESET
pin can be connected to an external reset source, see Figure 29 for a switch
example.
If the reset signal is connected to an output signal it must be an open drain collector, see Figure
30. Notice the capacitive load on the
RESET
pin in section 2.4.
The
RESET
pin can be left unconnected if not used.
