8.2.1 Under-Voltage Detection

Under-voltage detection is frequently required to alert the system that a battery voltage has dropped below the usable voltage level. Figure 23 shows a simple under-voltage detection circuit using the TLV3012-Q1 which is configured as a non-inverting comparator with the integrated 1.242V reference is externally connected to the inverting input pin (IN-).
