Standby (STBY) Pin

The Evaluation Board can control the F0448 for standby operation. The standby pin is the center pin of the J4 and J11 header as shown in

Figure 46. VCC (logic HIGH) and ground (logic LOW) pins are available to make a connection with a jumper.

Figure 46. Two Standby Pin Connections

To place channel A in the normal operation mode (on), use one of these options:



Make no connections on J4.



Apply a logic LOW signal to STBY (pin 2 of J4 or the middle pin).



Make a connection between pin 1 (GND) and pin 2 (STBY, the middle pin) of J4.

To place channel A in the standby mode (off), use one of these options:



Apply a logic HIGH signal to the STBY (pin 2 of J4 or the middle pin).



Make a connection between pin 3 (VCC) and pin 2 (STBY, the middle pin) of J4.

To place channel B in the normal operation mode (on), use one of these options:



Make no connections on J11.



Apply a logic LOW signal to STBY (pin 2 of J11 or the middle pin).



Make a connection between pin 1 (GND) and pin 2 (STBY, the middle pin) of J11.

To place channel B in the standby mode (off), use one of these options:



Apply a logic HIGH signal to the STBY (pin 2 of J11 or the middle pin).



Make a connection between pin 3 (VCC) and pin 2 (STBY, the middle pin) of J11.
