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.
