Description
Digital Select Pin 1. Used with SEL0 to select channels to be used (see Table 5).
Digital Select Pin 0. Used with SEL1 to select channels to be used (see Table 5).
Digital Select Pin 1. Used with DGT0 and DGT2 to select deglitch time (see Table 7).
Digital Select Pin 0. Used with DGT1 and DGT2 to select deglitch time (see Table 7).
Selects three separate alarms or one shared alarm. When ALRMSEL is logic high, three separate alarms are
selected; when ALRMSEL is logic low, one shared alarm is selected.
Selects NTC or PTC thermistor for VTx inputs. When NPTC is tied to logic high (LDO pin), a PTC thermistor is
selected; when NPTC is tied to logic low (VBOTx pin), an NTC thermistor is selected.
Ground. Tie to same potential as VBOT1 and VBOT2.
