UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
Only bits marked with (E2) in the register map have EEPROM programmable power-up default settings. All other bits keep the factory settings listed in the register map. Changing the power-up default values is not recommended in production but for prototyping only.
The EEPROM of a device can only be programmed up to 1000 times. The number of programming cycles should never exceed this amount. Contact TI for changing production settings.
EEPROM values can only be changed if the input voltage (VIN_BIAS) is greater than 4.5 V. If the input voltage is less than 4.5 V, EEPROM values remain unchanged and the VPROG interrupt is issued. EEPROM programming requires less than 100 ms. During this time the supply voltage must be held constant and all I2C write commands are ignored. Completion of EEPROM programming is signaled by the EE_CMPL interrupt.
All re-programmed EEPROM settings must be validated during prototyping phase to ensure desired functionality because parts cannot be returned in case of incorrect programming. Any issues should be reported to the e2e forum.
