Part Number: TPS3700
Other Parts Discussed in Thread: TPS3710

Hi,

According to the following application note, we can detect OV/UV for negative rail using TPS3700.

https://www.ti.com/jp/lit/an/slva600/slva600.pdf

But my customer wants to check UV only for -15V rail.  In other words, he wants to monitor around -13V on -15V rail.  Could you please let us know the right device?

Please advise us.

Thanks and best regards,
M.HATTORI.

    Hi Hattori 

    You can use TPS3700 with diode connected only on OUTA pin or you can use TPS3710 which is only UV monitor and has similar specs as TPS3700. 

    Let me know if you have further questions/Concern for accuracy , delay or any other spec. 

    Regards
