Figure 2. Ensuring Reset Valid down to V CC = 0
(Figure 2a). The pull-down resistor value is not critical;
100k ? is large enough not to load RESET , and small
enough to pull it low. For the MAX6335, where RESET
must be valid to V CC = 0, a 100k ? pull-up resistor
between RESET and V CC will hold RESET high when
V CC falls below 0.7V (Figure 2b).
Since the MAX6337 has an open-drain, active-low out-
put, it typically uses a pull-up resistor. With this device,
RESET will most likely not maintain an active condition,
but will drift to a non-active level due to the pull-up
resistor and the reduced sinking capability of the open-
drain device. Therefore, this device is not recommend-
ed for applications where the RESET pin is required to
be valid down to V CC = 0.
