8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 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.

8.1.1 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.
