The TLV6703-Q1 comparator has two inputs: one external input, and one input internally connected to the internal 400mV reference. The comparator rising threshold is trimmed to be equal to the reference voltage (400 mV). The comparator also has a built-in falling hysteresis that makes the device less sensitive to supply-rail noise and provides stable operation.

The comparator input (SENSE) is able to swing from ground to 6.5 V, regardless of the device supply voltage. Although not required in most cases, to reduce sensitivity to transients and layout parasitics for extremely noisy applications, place a 1-nF to 10-nF bypass capacitor at the comparator input.

OUT is driven to logic low when the input SENSE voltage drops below (V_IT-). When the voltage exceeds V_IT+, the output (OUT) goes to a high-impedance state; see Figure 7-1 .
