TPS65273V: How to set TPS65273V address to 0x61'h ?

Hi Alex,

Thanks for reaching out. Could you please check the address when you pull ADDR pin to 3.3V?

Hi Lucia,

I use the EN pin mask off other 2 TPS65273V. so only 1 device will respond to I2C command.

for the device ADDR using 10k ohm pull to 3.3V, it only ACK to 0x62'h

Hi Alex,

Do you mean that when you connect ADDR to Vcc or leave it open, they both shows 0x62H?

oh yes... I mixed it up

yes, whatever I connect ADDR pin to Vcc (3.3V) or let it open, the device only ACK to 0x62'h

Hi Alex,

It does not make sense to show 0x62h for different setup. What about if you connect to GND? Could you please share me the schematic to check the circuit of ADDR and dump the register?

Hi Lucia,

If I connect ADDR to GND TPS65273V will ACK on 0x60'h

If I remove the resistor it will ACK to 0x62'h and ADDR pin probed 1.8V

Below is my schematic, a 12V-to-0.674V network and control by EN1

Hi Lucia,

Thanks a lot. By shorting ADDR to V7V, IC will ACK to 0x61'h now.
