MIC2772  
Dual Voltage Supervisor  
General Description  
Features  
The MIC2772 is a dual power supply supervisor that  
provides under-voltage monitoring and power-on  
Two independent voltage supervisors  
Directly replaces discrete supervisors  
Generates power-on reset pulses  
De-bounced manual reset Inputs  
Choice of voltage thresholds  
20, 140, or 1100ms reset timeouts  
Reset output may be pulled above VCC  
Rejects brief input transients  
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.  
Ultra-small 2x2mm MLF package  
Applications  
Servers  
Embedded Controllers  
Telecommunications Systems  
Power Supply Sequencing  
Hot-swapping  
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.  
Power supplies  
The tiny 2x2mm MLF package has a footprint  
smaller than that of a single SOT23 voltage  
supervisor.
