Power sequence

2.9.1

Power up and boot sequence

There are two options available for device power up/boot.

Option 1: XSHUT pin connected and controlled from host.

This option helps to optimize power consumption as the VL53L0X can be completely

powered off when not used, and then woken up through host GPIO (using XSHUT pin).

HW Standby mode is defined as the period when AVDD is present and XSHUT is low.

Figure 10. Power up and boot sequence

tBOOT is 1.2ms max.

Option 2: XSHUT pin not controlled by host, and tied to AVDD through pull-up resistor.

In case XSHUT pin is not controlled, the power up sequence is presented in Figure 11. In

this case, the device is going automatically in SW STANDBY after FW BOOT, without

entering HW STANDBY.

tBOOT is 1.2ms max.
