TPS27S100: Current sense accuracy

user5883945

Part Number: TPS27S100
Other Parts Discussed in Thread: TIDA-01552

The TPS27S100 datasheet says that current sense accuracy is ±30mA in 1A load. But the reference design TIDA-01552 that used TPS27S100 says can get 5mA accuracy. is true?

Hi,

Please refer to the datasheet for the device specifications including the current sensing accuracy. Could you take a screenshot of where does the TIDA-01552 say that 5mA accuracy is achieved? Thanks.

Hi,

I just checked with the team and the statements in the reference design is outdated. Please use datasheet current sense accuracy percentage numbers as guidance. Thanks!
