Precise Detection Thresholds: Standard ?2.0%, The TC54 series are CMOS voltage detectors that are Custom ?1.0% especially well suited for battery-powered applications because of their extremely low 1 ?A operating current  Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89, and small surface-mount packaging. Each part is laser- TO-92 and 5-Pin SOT-23A (7.7V only) trimmed to the desired threshold voltage, which can be  Low Current Drain: Typ. 1 ?A specified from 1.4V to 7.7V for a 2% tolerance and from  Wide Detection Range: 1.1V to 6.0V and 7.7V 1.5V to 6.0V for a 1% tolerance.  Wide Operating Voltage Range: 0.7V to 10V The device includes a comparator, low-current high- precision reference, laser-trimmed divider, hysteresis Applications circuit and output driver.
