SC70/µDFN, Single/Dual Low-Voltage,
Low-Power µP Reset Circuits
General Description
The MAX6381–MAX6390 microprocessor (µP) supervisory
circuits monitor power-supply voltages from +1.8V to
+5.0V while consuming only 3µA of supply current at
+1.8V. Whenever V
CC
falls below the factory-set reset
thresholds, the reset output asserts and remains assert-
ed for a minimum reset timeout period after V
CC
rises
above the reset threshold. Reset thresholds are available
from +1.58V to +4.63V, in approximately 100mV incre-
ments. Seven minimum reset timeout delays ranging
from 1ms to 1200ms are available.
The MAX6381/MAX6384/MAX6387 have a push-pull
active-low reset output. The MAX6382/MAX6385/
MAX6388 have a push-pull active-high reset output,
and the MAX6383/MAX6386/MAX6389/MAX6390
have an open-drain active-low reset output. The
MAX6384/MAX6385/MAX6386 also feature a
debounced manual reset input (with internal pullup
resistor). The MAX6387/MAX6388/MAX6389 have an
auxiliary input for monitoring a second voltage. The
MAX6390 offers a manual reset input with a longer V
CC
reset timeout period (1120ms or 1200ms) and a shorter
manual reset timeout (140ms or 150ms).
The MAX6381/MAX6382/MAX6383 are available in
3-pin SC70 and 6-pin µDFN packages and the
MAX6384–MAX6390 are available in 4-pin SC70 and
6-pin µDFN packages.

after "XR", "XS", or "LT." Insert reset timeout delay (see Reset
Timeout Delay table) after "D" to complete the part number.
Sample stock is generally held on standard versions only (see
Standard Versions table). Standard versions have an order
increment requirement of 2500 pieces. Nonstandard versions
have an order increment requirement of 10,000 pieces.

Who is the source manufacturer of the 3651 orthogonal convex tooth sensor? Is there anyone who can be its agent?
When looking for a cam sensor with orthogonal output, I found MT3651 and YS3651 at the same time. Both were printed with 3651 and packaged in TO-94. The price on Taobao was ¥7+ (the latter is now ¥9),...

Which is faster for switching, MOS or Darlington?
MOS and Darlington can both output a certain current when used as switches. I have seen that most small switching power supplies use MOS as a switching element. Of course, the drive is ideal, and Darl...
