    1 General Description
    The AS1904/5/6 family is an ultra low-power supervisory
    circuit device.
    The device can be used to monitor the supply voltage of
    digital systems and microprocessors and initiate a reset
    when the voltage goes below a predefined threshold.
    The duration of the reset is 5/20/100/500ms (typ.) after
    the supply voltage has risen above the threshold.
    The device exhibits excellent reliability and can reduce
    application costs by eliminating all external components.
    The device is available with different output drivers:
    !
    The AS1904 has a push-pull driver with an active low
    reset.
    !
    The AS1905 uses the same output stage as the
    AS1904, but has an active high reset.
    !
    The AS1906 has an open drain output with active low
    reset.
    All devices operate down to a voltage of 1V.
    The reset thresholds are factory-trimmable between
    2.2V and 3.08V in steps of approximately 100mV.
    Each device of the AS1904/5/6 family is offered with four
    time-out periods of 5/20/100/500ms.
    The extremely low current consumption of only 150nA
    (typ) at 3.3V makes the device ideal for use in portable
    applications.
    All devices are available in a 3-pin SOT23 package.
