Description
The A6300 offers a high level of integration by combining
voltage regulation and voltage monitoring. The voltage
regulator has a low dropout ( typ. 380 mV at 100 mA )
and a low quiescent current (100
μ
A). The quiescent
current increases only slightly in dropout prolonging
battery life. Built-in protection includes a positive transient
absorber for up to 60 V (load dump) and the ability to
survive an unregulated input voltage of –20 V (reverse
battery). The INPUT may be connected to ground or a
reverse voltage without reverse current flow from the
OUTPUT to the INPUT. Upon the OUTPUT voltage rising
above V
, the reset output, whether RES or RES, will
remain active (RES = 1, RES = 0) for an additional time
of 50 ms. This allows the system voltage and the
oscillator of the microprocessor to stabilize before they
becomes fully active. When V
falls below V
, the
reset output goes active. Threshold voltage can be
obtained in different versions: 2 V, 2.4 V, 2.8 V, 3.5 V, 4 V.
