General Description:

The TC54 series are CMOS voltage detectors especially well-suited for battery-powered applications because of their extremely low 1 µA operating current and small surface-mount packaging. Each part is lasertrimmed to the desired threshold voltage, which can be specified from 1.4V to 6.0V with a 2% tolerance.

The TC54 is available with either an open-drain or complementary output stage. During operation, the 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, when it resets to a logichigh state.
