4-Pin μP Voltage Monitors
with Manual Reset Input
Interfacing to μPs with
Bidirectional Reset Pins
μPs with bidirectional reset pins (such as the Motorola
68HC11 series) can contend with the MAX811/MAX812
reset outputs. If, for example, the MAX811 RESET out-
put is asserted high and the μP wants to pull it low,

COMPONENTS
indeterminate logic levels may result. To correct such
cases, connect a 4.7k Ω resistor between the MAX811
RESET (or MAX812 RESET) output and the μP reset I/O
(Figure 3). Buffer the reset output to other system com-
