implementation to confirm system functionality.

9.1 Application Information

The TLV40x1 is a 4-pin, low-power comparator with a precision, integrated reference. The comparators in this

family are well suited for monitoring voltages and currents in portable, battery powered devices.

9.1.1 Monitoring (V+)

Many applications monitor the same rail that is powering the comparator. In these applications the resistor

divider is simply connected to the (V+) rail.
