GENERAL DEscriptION

The SGM826B, SGM827B and SGM828B are low-power and high-accuracy voltage detectors with fixed built-in delay time. The adjustable threshold range is 2.2V to 6V with increments of 0.1V, which greatly provides application flexibility. For the delay of the release signal, there are three options, 50ms, 100ms, and 200ms. The OUT pin is an N-channel open-drain output with active-low reset.

All devices are all available in Green SOT-23-5 and SC70-4 (R) packages. They are specified over the -40℃ to +125℃ operating junction temperature range.
