Below V(POR), the output cannot be determined. (2) Specified by design. (3) When VCC falls below the UVLO threshold, the output deasserts (SENSE_OUT goes low, SENSE_OUT goes high). Below V(POR), the output cannot be determined. 6 Submit Documentation Feedback Copyright © 2011–2015, Texas Instruments Incorporated Product Folder Links: TPS389 |
