4) Calculate R1
Monitoring Voltages Other than VCC
The MAX6457–MAX6460 can monitor voltages other than
VCC (Figure 12). Calculate VTRIP as shown in the
Programming the Trip Voltage (VTRIP) section. The moni-
tored voltage (VMON) is independent of VCC. VIN+ must
be within the specified operating range: 0 to VCC.
Interfacing to Voltages Other than VCC
The open-drain outputs of the MAX6457–MAX6460
allow the output voltage to be selected independent of
VCC. For systems requiring an output voltage other than
VCC, connect the pullup resistor between OUT, OUTA, or
OUTB and any desired voltage up to 28V (see Figure 13).
Monitoring Negative Voltages
Figure 14 shows the typical application circuit for moni-
toring negative voltages (VNEG) using the MAX6460.
Select a value for R1 between 25k
and 1M. Use the
following equation to select R2:
where VREF = 2.25V and VNEG < 0. VIN+ must always
be within the specified operating range: 0 to VCC.
