The TC54 Series are CMOS voltage detectors, suited especially for battery-powered applications because of their extremely low 1uA operating current and small surface-mount packaging. Each part is laser trimmed to the desired threshold voltage which can be specified from 1.1V to 6.0V, for a 2% tolerance. The device includes a comparator, low-current high-precision reference, laser-trimmed divider,hysteresiscircuit 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 VIN 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.
**3L TO-92 package (ZB) is no longer available due to the End of Life (EOL) status.
