9.2.1 Under-Voltage Detection
Under-voltage detection is frequently required in battery-powered, portable electronics to alert the system that a battery voltage has dropped below the usable voltage level. #SLVSCI74383 shows a simple under-voltage detection circuit using the TLV4041R1 which is a non-inverting comparator with an integrated 1.2 V reference and a push-pull output stage. The non-inverting TLV4041 option was selected in this example since the micro-controller required an active low signal when an undervoltage level occurs. However, if an active high signal was required, the TLV4051 option with an inverting input stage would be utilized.
