Part Number: TPS610333
Dear Team,
This is Banupriya from iWave Systems.
We are using the TPS610333DRLR boost regulator in our device. As part of our low battery cut-off implementation, we are controlling the EN (Enable) pin of boost regulator (TPS610333DRLR) to ensure that the device powers on only after the battery voltage reaches the desired threshold.
During our testing, we observed that the boost regulator starts generating the output voltage when the EN pin reaches approximately 1.0 V. As a result, the device enters the power-on state before the EN pin reaches the expected threshold.
However, according to the datasheet, the VEN_H (Enable Input High Threshold) is specified as 1.2 V, and we expected the boost regulator to remain disabled until the EN pin reaches this threshold.
Could you please let us know why the output voltage starts generating at approximately 1.0 V instead of 1.2 V? Additionally, is there any recommended hardware or software approach to ensure that the boost regulator remains completely disabled until the EN pin reaches the specified VEN_H threshold during the low battery cut-off condition?
Attached is the schematics for your reference.
We would appreciate your support and look forward to your response.
Thank you.
Best regards,
Banupriya
