    MIC2774 - Dual Micro-Power Low Voltage Supervisor
    Docket ↓
    Dual Micro-Power Low Voltage Supervisor General Description Features The MIC2774 is a dual power supply supervisor that
    provides undervoltage monitoring, manual reset capability,
    and power-on reset generation in a compact 5-pin SOT-23
    package. Features include two undervoltage detectors,
    one fixed and one adjustable, and a choice of reset
    outputs. One undervoltage detector compares VDD against
    a fixed threshold. Ten factory-programmed thresholds are
    available. The second, user-adjustable input is compared
    against a 300mV reference. This low reference voltage
    allows for the monitoring of voltages lower than those
    supported by previous supervisor ICs. Monitors two independent power supplies for
    undervoltage conditions One fixed and one user-adjustable input Choice of ten factory-programmed thresholds Adjustable input can monitor supplies as low as 0.3V Generates 140ms (min.) power-on reset pulse Manual reset input Choice of active-high, active-low, or open-drain activelow reset outputs Inputs may be pulled above VDD (7V abs. max.) /RST output valid down to 1.2V Ultra-low supply current, 3.5µA typical Rejects brief input transients IttyBitty™ 5-pin SOT-23 package Pin-compatible upgrade for MAX6306/09/12 The reset outputs are asserted at power-on and at any
    time either voltage drops below the programmed threshold
    voltage and remains asserted for 140ms (min.) after they
    subsequently rise back above the threshold boundaries.
    Manual reset functionality can be provided by a switch
    connected between ground and the /MR input. A wide
    choice of voltage thresholds provides for a variety of
    supply voltages and tolerances. Hysteresis is included to
    prevent chattering due to noise. Typical supply current is a
    low 3.5µA.
