VL53L3CX XSHUT pin problem in deep sleep

Postby fafeyto » Sat Apr 23, 2022 9:46 am

I have project using a VL53L3CX distance sensor. Also , I control it by ESP32. In normally, I can command to XSHUT pin. And I can read xshut pin of ESP32 that is 3V3 or 0V.

But, When ESP32 enters deep-sleep mode for current consumption, XSHUT pin of the ESP32 is 2V8. So, My power consumption is too high. Because I can not turn of the VL53L3CX sensor.

In addition, is it ok if i drive XHUT pin directly through ESP32 IO? (No pull up,no ESD protection resistor)

Has anyone encountered such a problem?
