TPS65987D: Figure 42 in Datasheet

David Mckinney

Part Number: TPS65987D
Other Parts Discussed in Thread: TPS65987

The pin numbers shown in Figure 42 in the datasheet for the TPS65987D do not match the Pin Description Table or the TPS65987 - 90EVM board schematic. Can you correct Figure 42?

There are many differences, but here are a few.

Pin	DataSheet Description	Figure 42
11	PP_HV1	VBUS_1
12	PP_HV1	VBUS_1
8	Drain1	ADCIN2
7	Drain2	LDO_3V3
9	LDO_3V3	PP_HV1
10	ADCIN2	PP_HV1
13	VBUS1	GPIO0
14	VBUS1	GPIO1
15	Drain1	GPIO2
16	GPIO0	GPIO5

Hi David,

Are you using the datasheet on ti.com under the TPS65987D product page? I cannot see these errors in that datasheet.

Please use the datasheet that is on Ti.com

Hi Eric; Yes, I was using the www.ti.com datasheet updated Aug. 2018. I went back and pulled the error from the online (downloaded) copy and attached an example. Note the signal name differences.

Hi David,

I've assigned this thread to Ghouse who is the owner of the TPS65987-90EVM.

Ghouse,

Could you please comment on Davids question regarding the pin numbering of the EVM?

Thank you,
Eric

Eric,

What David is talking about is not the EVM schematics but the Application schematics withing the datasheet. like in figure 33 or figure 44 of datasheet are incorrect.

David,

Thanks for catching the issue. We will look into this as soon as we can.

Best Regards,
Ghouse
