TIC10024-Q1: Sleep mode Leakege current

Hi, Youngsu,

When the TIC10024-Q1 is put into the sleep mode (polling mode) and when the input is not getting sampled, the leakage current for each input is the same as if the channel is disabled and it's spec'ed in the datasheet as below. The leakage current is specified regardless of whether the external switch input is ON of OFF as it is only a function of the voltage on the VINX pin and the temperature. 

Regards,

David

Dear David,

Thank you for answer.

We encounter the following phenomenon.

1. INx : S/W ON (GND)

2. Idle state

3. 60 ~ 80uA current per channel is confirmed (current increases as channel increases)

In the above conditions, it is necessary to confirm whether or not the setting is wrong.

Can you confirm the settings to reduce the current under the above condition?

Thanks.

Hi, Youngsu,

That seems a little bit too high. Can you confirm whether:

1. Where is the 60~80uA current measured at? Is in on the INx pin or on the supply (VS) pin of the device?
2. Can you confirm the settings in the idle state? Is TRIGGER bit 0 or 1 (polling disabled or enabled)? What is the setting for the current source (?mA) and is the channel being measured enabled (IN_EN_xx = 0 or 1)?
3. Is there any pending interrupt not serviced (/INT low and not read)? 

Thanks,

David
