Part Number: TPS659122EVM-081
Hi greeting:
We're under help our customer to debug the TPS659122 with Tof sensor (OPT8320) application.
They've feedback a problem about the voltage abnormal case when sending the code to call the register: 0x0Ah (DCDC3_OP), fail rate about 11/60 pcs and cant be duplicated
Through the I2C to call the DCDC Register memory map, it will get non-ack information, but get acknowledge OK when sending again. It always happened when set dcdc3_op this one.
We'd like to know is there anything suggestion to customer check their coding? or some point we could check again?
