1.4 Application schematic
Figure 3 shows the application schematic of the VL53L1X.
Figure 3. VL53L1X schematic
Note: Capacitors on external supply AVDD should be placed as close as possible to the
AVDDVCSEL and AVSSVCSEL module pins.
Note: External pull up resistor values can be found in I
2
C-bus specification. Pull ups are typically
fitted only once per bus, near the host. For suggested values see
Table 3.
Note: XSHUT pin must always be driven to avoid leakage current. A pull up is needed if the host
state is not known.
XSHUT is needed to use HW standby mode (no I
2
C communication).
Note: XSHUT and GPIO1 pull up recommended values are 10 kOhms
Note: GPIO1 to be left unconnected if not used
Table 3 show recommended values for the pull up and series resistors for an AVDD of 1.8 V
to 2.8 V in I
2
C Fast mode (up to 400 kHz).
