Warning:

Stresses above those listed in the following table may cause permanent damage to the device. These are stress ratings only. Functional operation of the device is not implied at these or any other conditions above those indicated in the operational sections of the specification. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Table 7. Absolute maximum ratings

There are no power supply sequencing requirements. The I/Os may be high, low, or floating when AVDD is applied. The I/Os are internally failsafe with no diode connecting them to AVDD.

Table 8. Recommended operating conditions

The following figure shows the application schematic of the VL53L0X.

Figure 3. VL53L0X schematic

Note:

Capacitors on the external supply AVDD should be placed as close as possible to the AVDDVCSEL and AVSSVCSEL module pins.

Note:

The external pull-up resistor values can be found in the I²C-bus specification. Pull-ups are typically fitted only once per bus, near the host. Recommended values for pull-up resistors for an AVDD of 2.8 V and a 400 kHz I²C clock are 1.5 k to 2 kOhms

Note:

The 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 hardware standby mode (there is no I²C communication).

Note:

The recommended value of the XSHUT and GPIO1 pull-ups is 10 kOhms.

Note:

The GPIO1 should be left unconnected if not used.
