Application Information

Monitoring Voltages Other Than V_CC

Monitoring a Negative Voltage

The IMP705-708 can monitor voltages other than V using the The Power-Fail circuitry can also monitor a negative supply rail.

Power Fail circuitry. If a resistive divider is connected from the When the negative rail is OK, PFO will be LOW, and when the

voltage to be monitored to the Power Fail input, PFI, the PFO negative rail is failing (not negative enough), PFO goes HIGH

(output) will go LOW if the divider voltage goes below its 1.25V (the opposite of when positive voltages are monitored). To trigger

reference. Should hysteresis be desired, connect a resistor (equal a reset, these outputs need to be inverted: adding the resistors

to approximately 10 times the sum of the two resistors in the and transistor as shown achieves this. The RESET output will

divider) between the PFI and PFO pins. A capacitor between PFI then have the same sense as for positive voltages: good = HIGH,

and GND will reduce circuit sensitivity to input high-frequency bad = LOW. It should be noted that this circuit’s accuracy depends

noise. If it is desired to assert a RESET in addition to the PFO flag, on the V_CCline, the PFI threshold tolerance, and the resistors.

this may be achieved by connecting the PFO output to MR.
