LBO pin does not go LOW in TPS61032 ic

Other Parts Discussed in Thread: TPS61032

Hi,

I have used R1 = 1M ohm, R2 = 270K ohm. So according to equation (3) in the datasheet of TPS61032, if my input voltage/VBAT is 2.35V or below it then the LBO should go low... But this does not happen and the LBO pin remains active high all the time. Please suggest what to do asap...

hi
i replied you in the other thread that "measure the voltage at LBI pin and make sure it is lower than 0.49V, and measure the voltage of LBO in the pin of the TPS61032". had you solve the problem? or had other observation.
