• Description: ?P Power-Supply Monitor with Reset
• Manufacturer: MAXIM [Maxim Integrated Products]

µPs with bidirectional reset pins, such as Motorola’s
68HC11 series, can contend with the MAX7705 reset
output. If, for example, the MAX7705 RESET output is
asserted high and the µP wants to pull it low, an inde-
terminate logic level may result. To correct this, con-
nect a 4.7kΩ resistor between the MAX7705 RESET
output and the µP reset I/O, as in Figure 3. Buffer the
RESET signal to other system components.
