MIC2772
Dual Voltage Supervisor
General Description
The MIC2772 is a dual power supply supervisor that
provides under-voltage monitoring and power-on
reset generation. It may replace two discrete
voltage supervisors such as MIC1810, MIC1815,
MIC809, MIC811, MIC6315, etc. The two voltage
supervisors are completely independent. Each
functional block features an under-voltage detector,
a delay-generator, and a de-bounced manual reset
input.
A wide choice of voltage thresholds is available.
The reset output is asserted at power-on and any
time the input voltage drops below the reference
voltage. It remains asserted for the chosen timeout
period after the input rises back above the threshold.
Reset timeouts of 20, 140, and 1100ms (minimum)
are available.
A reset can be generated at any time by asserting
the manual reset input, /MR. This input is internally
de-bounced, and the reset output will remain active
for the timeout period after the release of /MR. The
/MR input can also be used to daisy-chain one or
more of the MIC2772’s supervisors onto existing
power monitoring circuitry or other supervisors.
The tiny 2x2mm MLF package has a footprint
smaller than that of a single SOT23 voltage
supervisor.
