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 –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_TH, 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_OUTPUTfalls below V_TH, 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.
