TPS40090: TPS40090 Current-Sense Amplifier

Frank Mammen

Part Number: TPS40090

Hello TI-Team,

I want to feed the four current sense amplifiers by using four sinle current-transducer which gives an Offset Voltage of 2,5 V at 0 Amps. Want to connect 2,5 V to the CSCN-Pin to cancel the Offset Voltage.

Does it work with the internal CS-Amps?

Best regards

HI FrankM,

Where is current-transducer placed? Can you provide schematic or circuit diagram?

Can you consider regular DCR sensing method?

Thanks

Qian

Hi Qian,

Part of the schematic, DCR-sensing is no option, Uin=40V and Inductor too far away from TPS40090.
