TPS1212-Q1: TMR connection question

Ryker She

Part Number: TPS1212-Q1

Tool/software:

Hi expert,

Does the TMR pin have specific voltage range requirement, or it can be connected to any power rails which between -60 to 73V?

Does the TMR pin must be connected to between Rsns and MOSFET? Can we connect the TMP pin to VBAT or other power rails? And if we must connect the TMR pin and DRN pin together? Thanks.

Best Regards,

Ryker

Hi Ryker,

I am confused because you point to the TMP pin but are saying the TMR pin.

As long as VBATT/TMP are within the recommended operating ranges, the system should be fine.

Yes, the configuration needs to be as shown in the datasheet because of the internal structure.

TMP is only connected directly to VS if it is not used. TMP needs to be connected near the FET so it can accurately reflect the FET temperature.
