Power-Supply Monitor with Reset

Interfacing to µPs with

Bidirectional Reset Pins

Microprocessors with bidirectional reset pins (such as

the Motorola 68HC11 series) can contend with the

MAX709 reset output. If, for example the MAX709

RESET output is asserted high and the µP wants to pull

it low, indeterminate logic levels may result. To correct

this, connect a 4.7k

Ω resistor between the MAX709

RESET output and the µP reset I/O (see Figure 3).

Buffer the MAX709 RESET output to other system com-

ponents.
