ΔVRT AND ΔVCC(UVLO) = 0, except in Comparator Mode 2. IN COMPARATOR MODE, tRST = tPROP. PI FU CTIO S (MSOP/DFN Package) ADJ1 (Pin 10): Adjustable Voltage Input 1. Input to volt- age monitor comparator 1 (0.5V nominal threshold). The polarity of the input is selected by the state of the SEL pin (refer to Table 1). Tie to REF if unused (with SEL = VCC or Open). Exposed Pad (Pin 11, DFN Only): The Exposed Pad may be left unconnected. For better thermal contact, tie to a PCB trace. This trace must be grounded or unconnected. |
