Figure 4
the AC switch, a “power switch signal shaping” block used to read the AC switch state and a
buffer able to send the AC switch state to the MCU (AVF DRIVER). This signal should be
analyzed by the MCU, which can power-off the application in hazardous situations (for
example, to open a relay (SW) placed in the front-end of the application - see
Table 1
Figure 4.
Figure 5.
The STCC08 AVF driver block is used to send the AC switch state to the MCU. The AVF
output is an open collector and should be loaded with an external resistor or connected
directly to the MCU, in pull-up input configuration.
