I2C address map for STUSB4500?

HiWhich registers can be read/write on the STUSB4500? What are the register addresses?The datasheet only mentions the NVM parameters and their default values, how do you set them via i2c?ThanksJM

Hello, I am working on STC3117 for voltage and SoC detection. So far I am able to get voltage correctly but current values and SoC are wrong. Please check configuration if anything wrong.

Configurations are as followI am using default OCV table and 660mAh battery (4.2v max) with <70 mOhm internal impedancefirst OCV value = 7788REG_CTRLvBattTWI_Write(1, BATT_GAUGE_ADD, REG_CTRL, 0x02);REG_MODEvBattTWI_Write(1, BATT_GAUGE_ADD, REG_MODE,...

STNS01: LDO Output protection

Having 2 power rails, 3V3 and 5V while STNS01 generates 3V3 (well, 3V1 to be exact) from 5V input (or battery), is it possible to feed 3V3 externally when STNS01 is shutdown? Is STSN01's LDO output reverse protected? Or will we need an ideal diode to...
