The AWS703808 family of microprocessor
supervisory circuits monitors system voltages from
0.4 V to 5 V, asserting an open-drain RESETN
signal when the SENSE voltage drops below a
preset threshold or when the manual reset (MRB)
pin drops to a logic low. The RESETN output
remains low for the user-adjustable delay time after
the SENSE voltage and manual reset (MRB) return
above the respective thresholds.
The AWS703808 device uses a precision reference
to achieve 2.5% threshold accuracy for VIT ≤ 3.3 V.
The reset delay time can be set to 20 ms by
disconnecting the CT pin, 300 ms by connecting the
CT pin to VDD using a resistor, or can be useradjusted
between 1.25 ms and 10 s by connecting
the CT pin to an external capacitor. The
AWS703808 device has a very low typical
quiescent current of 2.4 μA, so it is well-suited to
battery-powered applications. It is fully specified
over a temperature range of -40°C to 125°C (TJ).
