Micro-Power Low Voltage Supervisor Advance Information
General Description
The MIC2776 is a power supply supervisor which provides under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. Features include an adjustable under-voltage detector, a delay-generator, a manual reset input, and a choice of active-high, active-low, or open-drain active-low reset output. The user-adjustable monitoring input is compared against a 300mV reference. This low reference voltage allows monitoring voltages lower than those supported by previous supervisor ICs. The reset output is asserted for no less than 140ms at poweron and any time the input voltage drops below the reference voltage.
