Figure 2. Ensuring Reset Valid down to VCC = 0
Ps and circuitry do not operate when VCC drops below
1V. For the MAX6804 application where RESET must be
valid down to 0, adding a pulldown resistor between
RESET and GND removes stray leakage currents, hold-
ing RESET low (Figure 2a). The pulldown resistor value
is not critical; 100k
is large enough not to load RESET,
and small enough to pull it low. For the MAX6803, where
RESET must be valid to VCC = 0, a 100k
pullup resistor
between RESET and VCC will hold RESET high when
VCC falls below 0.7V (Figure 2b).
Since the MAX6805 has an open-drain, active-low out-
put, it typically uses a pullup resistor. With this device,
RESET will most likely not maintain an active condition,
but will drift to a non-active level due to the pullup
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 VCC = 0.
