P Power Supply Supervisor With Battery Backup Switch
rev 1.0
October 2003
Monitoring Capabilities Of The Power-fail Input:
Although designed for power supply failure monitoring, the
PFI pin can be used for monitoring any voltage condition that
can be scaled by means of a resistive divider. An example is
the negative power supply monitor configured in Figure 8. In
this case a good negative supply will hold the PFI pin below
1.25V and the PFO pin will be at logic “0”. As the negative
voltage declines, the voltage at the PFI pin will rise until it
exceeds 1.25V and the PFO pin will go to logic “1”.
