The SGM8770 consists of two independent voltage comparators that are designed to operate from a single power supply or dual power supplies over a wide voltage range. For dual supplies application, the difference between the two supplies is 2.8V to 36V. Input common mode voltage is 1.5V lower than +VS. Low supply current is independent of the supply voltage. The outputs can be connected to other open-drain outputs to achieve wired-AND relationships.
The SGM8770 is available in Green SOIC-8 and TDFN-3×3-8L packages. The SGM8770 is specified over the extended -40℃ to +125℃ temperature range.
