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 µA). 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 â20 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 VTH, 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 VOUTPUT falls below VTH, 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.
