GENERAL DESCRIPTION

The TC54 Series are CMOS voltage detectors, suited especially for battery-powered applications because of their extremely low 1μA operating current and small surfacemount packaging. Each part is laser trimmed to the desired threshold voltage which can be specified from 2.1V to 6.0V, in 0.1V steps.

The device includes a comparator, low-current highprecision reference, laser-trimmed divider, hysteresis circuit and output driver. The TC54 is available with either an opendrain 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.
