6.1 Absolute maximum ratings

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 12. Absolute maximum ratings

6.2 Recommended operating conditions

Table 13. Recommended operating conditions

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.

| Parameter | | Min. | Typ. | Max. | Unit | |-----------|----------------|------------------|------|------|------|---| | | Voltage (AVDD) | | 2.6 | 2.8 | 3.5 | | | IO (IOVDD) (1) | Standard mode | 1.6 | 1.8 | 1.9 | V | | | | 2V8 mode (2) (3) | 2.6 | 2.8 | 3.5 |

• 1. XSHUT should be high only when AVDD is on.
• 2. SDA, SCL, XSHUT, and GPIO1 high levels have to be equal to AVDD in 2V8 mode.
• 3. The default driver mode is 1V8. 2V8 mode is programmable using the device settings loaded by the driver. For more details, refer to the VL53L1X API user manual (UM2356).

6.3 Electrostatic discharge

The VL53L1X is compliant with the ESD values presented in the following table.

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.

The storage temperature (TSTG) is the ambient temperature at which the device can be stored with no voltage applied.
