Hi Shinichi-san,

The maximum input/output current of the ADIM/HD pin and EN/PWM pin of the TPS923652/53 is not available. Maybe could you pls kindly share me how will customer plan to configure ADIM and EN/PWM? 

Thank you!

Hi Lucia,

Thank you for your reply.

I'll confirm with the customer.

Could you please wait for a couple of time.

I appreciate your great help and cooperation.

Best regards,

Hi Lucia,

I could obtain the customer's comment.

Could you please advise?

---

I plan to use an open-drain comparator such as the TLV1821 (TI).

When Vout is low, depending on the current value flowing through the comparator, Vout may not fall completely to near 0, so I need to know the input and output current values ​​of the ADIM/HD pins.

I would appreciate your advice.

Hi Shinichi-san,

The ADIM and PWM/EN are high impedance input pin. As the current is quite low, we don't have an exact value of it. But you can look at the EC table and make sure you are aware of the high low level threshold.

Thank you so much!

HI Lucia,

Thank you for your reply.

However, From your answer, it is not possible to determine whether the comparator's VOL exceeds 0.4V.
What is the order of the current at ADIM and PWM/EN pin ? uA, nA, or pA?

I think it is often a few μA, what about in the case of TPS923652?

I appreciate your great help and cooperation.

Best regards,

Shinichi

Hi Lucia,

Thank you for your reply.

I understand the current of ADIM and PWM/EN pin is few uA.

I'll share this information with the customer.

When the customer has an additional question, I consult you again.

I appreciate your great help and cooperation.

Best regards.
