Micro-Power Voltage Supervisor
Advance Information
General Description
The MIC2775 is a power supply supervisor that provides
under-voltage monitoring, manual reset capability, and power-
on reset generation in a compact 5-pin SOT package. Fea-
tures include an under-voltage detector, a delay generator, a
manual reset input, and both active-high and active-low reset
outputs. The under-voltage detector compares V
DD
against
a fixed threshold. Ten factory-programmed thresholds are
available.
The reset outputs are asserted for no less than 140ms at
power-on and any time the input voltage drops below the
reference voltage. It remains asserted for the timeout period
after the input voltage subsequently rises back above the
threshold boundary. A reset can be generated at any time by
asserting the manual reset input, /MR. This reset output will
remain active at least 140ms after the release of /MR. The
/MR input can also be used to daisy-chain the MIC2775 onto
existing power monitoring circuitry or other supervisors.
Hysteresis is included to prevent chattering due to noise.
Typical supply current is a low 3.5
