Re: Laser TOF Sensor (VL53L1CXVOFY/1) power supply... - STMicroelectronics Community

Hi, We are using Laser TOF Sensor (VL53L1CXVOFY/1) in one of our products.

Can we use AVDD=1.8V power supply? Even though AVDD = 2.8V, it looks like IOs will work on 1.8V.

Hi,

>> Can we use AVDD=1.8V power supply?

Please follow the datasheet if you want the device to operate normally:

Table 14. Recommended operating conditions

2.6V < AVDD < 3.5V

Hi Mike,

Laser TOF Sensor (VL53L1CXVOFY/1) power supply?

If we connect AVDD (Pin 11) and AVDDVCSEL (Pin 1) to 2.8V, Are the IOs still operate on 1.8V mode as given in Datasheet page number 23, Table 14.

Please check the datasheet, there are 2 modes, "standard mode" which is (1.8V) and 2V8 mode :

Section 5.2:

The default driver mode is 1V8.

2V8 mode is programmable using device settings loaded by the driver. For more details please refer to the

VL53L1X API user manual (UM2356).
