MIC2772
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 2mm x 2mm MLF® package has a footprint smaller than that of a single SOT23 voltage supervisor.
