TC54
General Description
The TC54 Series are CMOS voltage detectors that are especially well suited for battery-powered applications because of their extremely low 1 µA operating current and small surface-mount packaging. Each part is laser-trimm ed to the desired threshold voltage, which can be specified from 1.4V to 7.7V for a 2% tolerance, and 1.5V to 6.0V for a 1% tolerance. The device includes a comparator, low-current highprecision reference, laser-trimmed divider, hysteresis circuit and output driver. The TC54 is available with either an open-drain or complementary output stage. In operation, the TC54's output (VOUT) remains in the logic-high state as long as V IN is greater than the specified threshold voltage (VDET -). When VIN falls below VDET-, the output is driven to a logic-low. VOUT remains low until VIN rises above VDET - by an amount VHYST, whereupon it resets to a logic-high. TC54VC only
