Part Number: LP5024

Hello expert,

Customer has below questions and could you kindly help to check on it? Thanks a lot!

Q1 : Do we have flow chart to initialize?

Q2 : About auto-increment function, could you give us example for it?

Q3 : Do we have I2C recovery architecture? Customer's EC team need recovery architecture to prevent I2C latch issue occurred.

Best regards,

q1: You can refer to datasheet 8.4 Device Functional Modes.

q2: It's simple. For example you want to write registers 00h to 09h, then you just need to send the address of 00h and then the 10 bytes data using auto increment.

q3: LP5024 is i2c slave, so if the mcu send the correct i2c instruction then it responses.

Hello Kenneth,

Thanks for reply. So for Q3, it means there is no I2C refresh architecture if we pull low I2C DATA/CLOCK to GND for certain period. Since they are afraid that I2C Bus is latch, they will recover I2C Bud through this architecture. Thanks a lot!

Best regards,

Ann Lien
