General Description
The TC54 series are CMOS voltage detectors that are
especially well suited for battery-powered applications
because of their extremely low 1 A operating current
and small surface-mount packaging. Each part is laser-
trimmed 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 com-
plementary 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 logic-
high state.
