TPS2H160-Q1: some small bugs in the datasheet

Britton Kerin

Part Number: TPS2H160-Q1

Page 14, section 8.3.2, includes this "The current mirror is shared by the four channels". I think for this device it should read "The current mirror is shared by the two channels"

Page 26, Fig. 38, the resistor connecting the CS pin the the uc is not labeled. I think it should be labeled R(ser) like the other resistors between device and uc?

Please confirm, thanks

Hi Britton,

Thank you for pointing out these observations. I will reach out to the team for these devices and see if they were a mistake.

Thanks,

Another oddity: The Pin Functions table in Section 6 states that THER has an internal pulldown but section 9.2 Typical Application shows THER tied to ground externally. If there's an internal pulldown one would not expect to have to tie the pin low externally. So is there an internal pulldown or not, and if there is why the external tie to ground?

Hello, Britton,

Thanks for your great feedback!
1) share by four channels--> should be two.
2) R(ser), you are right.
3) Yes. It has internal weak pull-down, externally pulling-down can enhance the noise-rejection capacity.

Alex,
