The device’s Reset voltage trip point (V
when the device is ordered. As the voltage on the
device’s V
point, the output of the Reset pin (RST/RST) will be
forced to either the inactive or active state.
For the voltage trip point, there is a minimum trip voltage
(V
voltage that the device “actually” trips at will be referred
to as V
the device V
There is also a hysteresis (V
is so that noise on the device voltage (V
cause the Reset pin (RST/RST) to “jitter” (change
between driving an active and inactive).

The Reset pin (RST or RST) will be force active if any
of the following occur:
• The Manual Reset input (MR) goes low
• The Watchdog Timer times out
• V
• During device power up
After the device exits the Reset condition, the delay
circuitry will hold the RST and RST pins active until the
