This datasheet introduces TC54 Series CMOS voltage detectors, suitable for battery-powered applications due to their extremely low operating current of 1µA 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 and 7.7V, for a 2% and 1.5V to 6.0V for a 1% tolerance. The device includes a comparator, low-current high-precision 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 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.
The TC54 series are CMOS voltage detectors designed for battery‑powered applications. The handbook describes precise detection thresholds, low current drain, wide detection range (1.1 V‑6.0 V and 7.7 V) and operating voltage (0.7 V‑10 V). It includes a functional block diagram, pin‑out tables for 3‑Pin SOT‑23A, 3‑Pin SOT‑89 and 5‑Pin SOT‑23A packages, and detailed electrical specifications.
Packaging information covers tape orientation, reel sizes and mechanical dimensions for each package type. The document also lists typical applications such as battery monitoring, microprocessor reset and brown‑out protection, and provides legal and worldwide sales contact details.
