Overview
MIC2775 Micro-Power Voltage Supervisor IttyBitty® General Description The MIC2775 is a power supply supervisor that provides undervoltage monitoring, manual reset capability, and power-on reset generation in a compact 5-pin SOT package.
Features include an undervoltage detector, a delay generator, a manual reset input, and both activehigh and active-low reset outputs.
The undervoltage detector compares VDD 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 daisychain the MIC2775 onto existing power monitoring circuitry or ot...
