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.
