AS1977

The AS1976/AS1977 are very low-current comparators that can operate beyond the rail voltages and are guaranteed to operate down to 1.8V Low input bias current, current-limiting output circuitry, and ultra-small packaging make these comparators ideal for low-power 2-cell applications including power-management and power-monitoring systems.

The comparators are available as following standard products:

Model	Output Type	Current
AS1976	Push/Pull	200nA
AS1977	Open-Drain	200nA

The AS1976 push/pull output can sink or source current.

The AS1977 open-drain output can be pulled beyond VCC to a maximum of 3.6V > VEE. These open-drain versions are ideal for use as logic-level translators or bipolar-to-unipolar converters.

Large internal output drivers provide rail-to-rail output swings with loads up to 8mA. All devices feature built-in battery power-management and power-monitoring circuitry.

The AS1976/AS1977 are available in a 5-pin SOT23 package.
