4.2.3
POWER-DOWN/BROWN-OUT
As the device powers-down/browns-out, the VDD falls
from a voltage above the devices trip point (VTRIP). The
device will trip at a voltage between the maximum trip
point
(VTRIP(MAX)) and the minimum trip point
(VTRIP(MIN)). Once the device voltage (VDD) goes
below this voltage, the RST/RST pin will be forced to
the active state. Table 4-3 shows the state of the RST
or RST pins.
Figure 4-8 shows the waveform of the RST pin as
determined by the VDD voltage. As the VDD voltage falls
from the normal operating point, the device “enters”
Reset by crossing the VTRIP voltage (between
VTRIP(MAX) and VTRIP(MIN)). Then, when VDD voltage
rises, the device “exits” Reset by crossing the VTRIP
voltage (below, or at, VTRIP(MAX)). After the “exit” state
has been detected, the Reset Delay Timer (tRST) starts.
When the tRST time completes, the Reset pin is driven
inactive.
