8.1 Overview

The TLV6703-Q1 provides precision voltage detection. The TLV6703-Q1 is a wide-supply voltage range (1.8 V to 18 V) comparator with a high-accuracy rising input threshold of 400 mV (1% over temperature) and built-in hysteresis. The output is also rated to 18 V, independant of supply voltage, and can sink up to 40 mA.

The TLV6703-Q1 asserts the output signal, as shown in Table 8-1. To monitor any voltage above 0.4 V, set the input using an external resistor divider network. Each input pin has very low input leakage current, allowing the use of large resistor dividers without sacrificing system accuracy. Broad voltage thresholds are supported that enable the device for use in a wide array of applications.
