Packages The LTCВ®2966 is a low current, high voltage dual channel
voltage monitor. Internal high value resistors sense the
input monitor pins providing a compact and low power
solution for voltage monitoring. Each channel includes
two comparator reference inputs (INH/INL) to allow configuration of a high and low threshold using an external
resistive divider biased from the on-chip reference. Range
selection pins are provided for each channel to set the
internal resistive dividers for 5x, 10x, 20x and 40x scaling.
The thresholds are scaled according to the range selection
settings. Additionally, either INH or INL can be grounded
to enable built-in hysteresis. Polarity selection pins allow …
