PRODUCTION DATA
The TLV40x1 devices are low-power comparators that are well suited for compact, low-current, precision voltage detection applications. With high-accuracy, switching thresholds options of 0.2V, 0.5 V, 1.2V, and 3.2V, 2uA of quiescent current, and propagation delay of 450ns and 2us, the TLV40x1 comparator family enables power conscious systems to monitor and respond quickly to fault conditions.
The TLV40x1Ry comparators assert the output signal as shown in #GUID-BF9F0054-8B9C-4EFF-A517-CE8CE92F2203/SNVSB045081. VIT+ represents the positive-going input threshold that causes the comparator output to change state, while VIT- represents the negative-going input threshold that causes the output to change state. Since VIT+ and VIT- are factory trimmed and warranted over temperature, the TLV40x1 is equally suited for undervoltage and overvoltage applications. In order to monitor any voltage above the internal reference voltage, an external resistor divider network is required.
The TLV4021S5x functions similar to the TLV40x1Ry comparators except the resistor divider is internal to the device. Having the resistor divider internal to the device allows the TLV4021S5x to have switching thresholds higher than the internal reference voltage of 1.2V without any external components.
