Functional Description
General
During start-up, the reset pin on a microprocessor
ensures that it is fully reset and starts up in a known
condition. The AAT3520 series of microprocessor
reset devices monitor the supply voltage to a micro-
processor and assert a reset signal whenever the
V
CC
voltage falls below a factory programmed
threshold. This threshold is accurate within +/-1.5%
at 25oC and within +/- 2.5% over the entire operat-
ing temperature range. The reset signal remains
asserted for a fixed time period (t
RDY
) after V
CC
has
risen above the threshold as shown in Figure 1.
See Ordering Information for available RESET
active timeout periods
