Interfacing to Other Voltages
for Logic Compatibility
The open-drain RESET output can be used to interface
to a P with other logic levels. The open-drain output is
connected to a voltage from 0V to 5.5V as shown in
Figure 5. Generally, the pullup resistor connected to
RESET connects to the supply voltage that is being
monitored at the device’s VCC input. However, some
systems use the open-drain output to level-shift from
the supervisor’s monitored supply to another supply
voltage. As the supervisor’s VCC decreases, so does
the device’s ability to sink current at RESET.
Ensuring a Valid
RESET Down to VCC = 0V
(Push-Pull
RESET)
When VCC falls below 1.1V, the current-sinking capabil-
ity of RESET decreases drastically. The high-imped-
ance CMOS logic inputs connected to RESET can drift
to undetermined voltages. This presents no problems in
most applications, since most Ps and other circuitry
do not operate with VCC below 1.1V. In those applica-
tions where RESET must be valid down to 0, add a pull-
down resistor between the MAX16056/MAX16057
push-pull RESET output and GND. The resistor sinks
any stray leakage currents, holding RESET low (Figure
6). Choose a pulldown resistor that accommodates
leakages, such that RESET is not significantly loaded
and is capable of pulling to GND. The external pull-
down cannot be used with the open-drain RESET out-
put of the MAX16058/MAX16059.
